Where the most credit card transactions per person takes place -- read: serious shopping addictions. While foreign luxury goods tend to get a hefty mark up, local boutiques tend to be cheap and very chic. 
Home to what many fashion industry insiders consider the world's most important fashion district, the Quadrilatero della Moda, Milan gave the world Prada, Versace, Dolce & Gabbana and many more high-fashion brands. 
Madrid ranks third for best prices on luxury items in the Globe Shopper Index. We love it for the glorious sidewalks. 
Dubai is known for glamour and excess; the shopping here would have your Scottish/Chinese/Indian/Great Depression grandmother spinning in her inexpensive plywood coffin. Home to the world's largest mall, Dubai is also home to an indoor ski resort ... at a mall. 
Vienna's early closing hours don't have to be a total buzz kill. It has some of the best values in Europe, second on the index for total cost of luxury items. 
How many styles can you pack into one place? Buenos Aires is famous for leather and jewelry and style-obsessed citizens. 
"Shopping is one of, if not the, major attraction in Hong Kong. The city ranks highly across most indicators, not least for convenience," says the Global Shopper Index, which deems Hong Kong the best shopping city in Asia. According to the research, 76% of shopping tourists "expressed above-average satisfaction on value for money in 2011." 
The best shops in Paris sell lifestyles. Case in point: Whimsical shop Merci stocks designer goods that fall under the category of utterly useless but absolutely irresistible. 
Bigger is better in the mind of Kuala Lumpur shopper's ethics. Three of the world's 10 largest malls are in Kuala Lumpur, and the number one mall Utama has more than 650 shops, Asia's largest indoor rock climbing facility and a massive rooftop garden. 
London prices can destroy your will to live. But get over the sticker shock and you'll see London shopping at its best. Bold, eclectic and international, Liberty department store will inspire you to buy things you never knew existed. 
The best of Tokyo shopping can be found in the department store. Isetan's mammoth flagship in Shinjuku has shopping consultants who will advise customers on everything from shoes to fish. 
Where personal stylists and designer showrooms (and better yet, discounted designer showrooms) abound, New York's exclusive shopping experiences include curated vintage shopping, fashion history tours and discount mega-department stores.

- Quadrilatero della Moda in Milan is considered the world's most important fashion district
- Three of the world's 10 largest malls are in Kuala Lumpur
- The ultimate Tokyo shopping experience is the department store
(CNN) -- It may be mid-November but in Hong Kong and other parts of the world, Christmas decorations are disturbingly already up. Beautifully packaged gift goodies are rolled out in stores. Snow scenes and reindeer take up residence in shopping malls even in the southern hemisphere.
The organized cross off items on shopping lists. The unorganized try to remember to remember to buy presents for loved ones.
From a shopper's perspective, frequent traveling can be crippling. It can get worse in the holiday season where Christmas dominates many people's calendars. Why buy something in one city when a trip to a better shopping city is coming up?
To pinpoint which cities around the world deliver the most gratifying, enjoyable shopping experiences, we consulted global experts, such as fashion merchandising firm Donegar Creative Services and Marie Bergfelt, senior spokesperson for Global Blue, which publishes the Globe Shopper City Index.
Then we judged cities in four areas, using a one-to-10 scoring scale for each category:
1. Getting around: Quality of public transportation, affordability and availability of cabs, transport time
2. Value: Bargain opportunities, such as sale seasons and average prices.
3. Variety: Number of available brands, range of shopping categories, quantity of upscale shops, department stores, boutique and vintage retailers and market stalls.
4. Experience: City beauty, quality of window displays and shop décor, friendliness and competence of clerks and service staff, dining and accommodation options.
Then we charged into the breach.
12. Seoul
Getting around: 4 Value: 7 Variety: 4 Experience: 6 Total: 21
Fact: South Korea has a serious addiction to shopping. The most serious in the world, in fact.
South Korea recorded more credit card transactions per person than any other country in 2011, and all merchants are required by law to accept credit cards no matter how low the price. Yes, that means the phrase "cash only, please" is technically illegal.
This translates to a capital city bursting with shops of a dizzying array of types and sizes, from LED-fish-scale-studded luxury department stores to towering all-nighter shopping malls to trendy street carts, which all reflect the ever-changing hottest item of the moment.
While foreign luxury goods tend to get a hefty mark-up (except at the airport, which boasts the first Louis Vuitton airport duty free store, as well as cheap prices for most foreign brands), local boutiques tend to be cheap and chic.
The city also has a good mix of the old and new, according to the Globe Shopper Index, which recommends the Seoul Folk Flea Market, Namdaemun Market and Gyeongdong Market for a shopping spree of more traditional goods.

11. Milan
Getting around: 5 Value: 5 Variety: 4 Experience: 8 Total: 22
Home to many of fashion's biggest names such as Prada, Dolce & Gabbana and Versace, it's little wonder this beautiful city is full of glamorous locals and shops that cater to them.
One of the most beautiful (if expensive) shopping experiences can be found at Quadrilatero della Moda or Quadrilatero d'Oro ('rectangle of gold'), which many fashion insiders consider is the world's most important fashion district.
The interwoven pedestrian streets are lined with jewelers, boutiques and lifestyle showrooms that make for great window shopping.
While the boutiques cater to the alligator-bag-and-black-card-toting crowd, luckily for bargain shoppers, yesterday's styles are tossed aside so fast, outlets and sales racks are always full.
Il Salvagente ("the lifesaver"), Milan's best known and longest established outlet, has three floors of goods discounted up to 60%, all organized by size and color.
No one back home needs to know it was bought at an outlet mall -- Milan fashions are always months ahead of the trends elsewhere.
Whip out the plastic at:
Quadrilatero d'Oro, between via Montenapoleone, via Borgospesso, via Della Spiga and via Sant' Andrea, Milan
Il Salvagente, Via Fratelli Bronzetti 16, 20129 Milan; +39 02 7611 0328; Monday 3 p.m.-7 p.m., Tuesday-Saturday, 10 a.m.-7 p.m.

10. Madrid
Getting around: 6 Value: 6 Variety: 4 Experience: 7 Total: 23
Madrid mostly gets our credit cards warm simply for being Madrid, though it's worth noting that the city ranks third for best prices on general luxury items in the Globe Shopper Index.
But we can't wow our friends with statistics (not our shopping friends, anyway), so what about the goods?
When searching for items unique to Madrid, we fell in love with Capas Seseña.
Established in 1901, the shop sells traditional wool and cotton velvet capes for men and women. The clientele includes Pierce Brosnan and Hillary Clinton. Picasso was reportedly buried in his cape from the store.
Casa de Diego stocks souvenir-worthy fans, mantillas, ornamental combs and even castanets. But what we really wanted to take home was one of its work-of-art statement umbrellas with engraved silver handle (€325/US$415).
Whip out the plastic at:
Capas Seseña, Calle de la Cruz, 23, 28012 Madrid, Community of Madrid; +34 915 316 840; Monday-Friday 9 a.m.-2 p.m., 5-8:15 p.m., Saturday 10 a.m.-2 p.m. and 4-8 p.m.

9. Dubai, United Arab Emirates
Getting around: 6 Value: 6 Variety: 8 Experience: 4 Total: 24
A miniature kingdom unto itself, the Dubai Mall is the world's largest mall in total area, with theme parks, a waterfall, "dancing" fountains, Olympic-sized ice rink, aquarium, indoor souk and malls within the mall, such as the Galeries Lafayette from France and the first Bloomingdale's outside the United States.
If that isn't enough cash registers, there's also the Mall of the Emirates, with the first indoor ski resort in the Middle East.
The Dubai Mall also hosts the annual Dubai Shopping Festival in January and February. We assume it's called a festival because they have fireworks, but it's really about package deals and discounts -- up to 70% on electronics, clothing and popular items.
The 2014 Festival starts January 2 and runs until February 2.
Whip out the plastic at:
Dubai Mall, Doha Street, Dubai; +971 4 362 7500; Monday-Wednesday and Saturday-Sunday 10 a.m.-10 p.m., Thursday-Friday 10 a.m.-11:30 p.m.

8. Vienna
Getting around: 6 Value: 8 Variety: 3 Experience: 8 Total: 25
With some of the earliest closing hours out of all the cities on the Globe Shopper Index, Vienna is tricky for shopping.
Total buzz kill, right?
But it also has some of the best values in Europe, coming in second on the Index for total cost of luxury items.
At the centuries-old Naschmarkt, shoppers can eat their way along 1.5 kilometers of 120 food vendors flogging local eats from kaiserschmarrn (dessert pancakes) and crepe-like palatschinke to exotic cheeses and seafood.

During Christmas season, they can browse through glass baubles and handcrafted ornaments while sipping on glühwein at Vienna's venerable and gloriously lit Christmas markets, the Platonic ideal of a fairy tale Christmas.
That's good for an extra "Experience" point and an eighth-place finish.
Whip out the plastic at:
Naschmarkt, 1060 Vienna; +43 1 5463405430; Monday-Friday 6 a.m.-7:30 p.m., Saturday 6 a.m.-6 p.m.

7. Buenos Aires
Getting around: 6 Value: 8 Variety: 6 Experience: 7 Total: 27
Sexy Argentine dance moves + sexy Argentine climate = sexy Argentine shopping.
Yes, the formula sort of sometimes works like that, especially when you're stalking high-quality leather at affordable prices.
Established in Buenos Aires in 1952, Mocasines Guido sells leather shoes for men; today there are three locations in Buenos Aires.
Calle Murillo is a street with leather shops that also offer tailoring services. Murillo 666 is perhaps the best known, but about 50 more surround it, a handy surfeit of shops come haggle time.

Moscasines Guido, Rodríguez Peña 1290, Buenos Aires; +54 11 4813 4095; open Monday-Friday 9:30 a.m.-7:30 p.m., Saturday 9:30 a.m.-1 p.m.

6. Hong Kong
Getting around: 10 Value: 5 Variety: 6 Experience: 7 Total: 28
Hong Kong's shop clerks are borderline stalkers -- in a good way.
If you don't know where you're going, they'll follow you around till you find it. If you don't know what you want, they'll tell you.
But the obsessive help can come in handy, especially if it leads to a world-class bargain.
According to Global Shopper City Index research, 87 percent of Hong Kong tourists shop, and "76 percent of shopping tourists expressed above-average satisfaction on value for money in 2011." Small wonder that Hong Kong also claims the title of best Asian shopping city in the Index.

For a bespoke shopping experience that involves local color, we hit up individual boutiques.
Fang Fong Projects in Central stocks womenswear from local label Fang Fong, which is like a Shanghai Tang that you'd actually wear often -- modern clothes with tasteful Asian touches.
Frequented by celebrities, KniQ stocks one-of-a-kind items like artfully ripped stockings (HK$320/US$41), and a selection of jumpsuits for men that costs upward of HK$2,000 ($250).

Fang Fong Projects, 67A Peel St., Central, Hong Kong; +852 3105 5557; open daily 2-8 p.m.
The hippest district in town: The likes of WDSG, Kapok, Club Monaco Men's Store, Monocle are found in in Star Street Precinct in Wanchai (Star Street, Moon Street, Sun Street) and St. Francis Yard.
5. Paris
Getting around: 6 Value: 6 Variety: 8 Experience: 9 Total: 29
The best shops in Paris don't sell clothes. They sell lifestyles.
Whimsical concept shop Merci stocks a selection of designer goods that fall under the category of utterly useless but absolutely desirable, such as art deco Bakelite switches. It's housed in an airy and vaguely bucolic space that includes a secondhand bookshop, florist and café. In addition to the Annick Goutal scent line, Merci stocks apparel by Stella McCartney and Yves St Laurent, often with deep discounts.

Colette offers reduced prices on designer goods. Then again, if you're like us, whatever you save on a Fendi dress might be spent on stylin' necessities like a bottle of Bling H2O, which comes in a frosted glass bottle decorated with Swarovski crystals. It's available for about US$50 at the downstairs "water bar," which has more than 70 brands of bottled water.
And, of course, there's the holy trinity of Parisian department stores:
Le Bon Marché dates to the 1850s. It's famed for a monster section of gourmet food (5,000 choices strong).
Printemps has the world's largest beauty department. This year the store is partnering with Christian Dior for an exclusive line.
Extravagant Galeries Lafayette is housed in a seven-story art nouveau structure with an entire floor dedicated to lingerie. Every Friday at 3 p.m. there's a free fashion show with English commentary. Reservations required, either by emailing welcome@galerieslafayette.com or calling +33 1 42 82 36 40.

4. Kuala Lumpur
Getting around: 6 Value: 10 Variety: 8 Experience: 6 Total: 30
Sometimes bigger really is better.
That's the prevailing shopper's ethic in Kuala Lumpur, anyway.
Three of the world's 10 largest malls are in KL, including 1 Utama, the world's fourth-largest mall with more than 650 shops, Asia's largest indoor rock climbing facility, massive rooftop garden with 500 species of exotic plants and indoor rainforest with koi ponds and freshwater aquarium.
KL's impressive score comes from its winning combination of high quality shopping, affordable prices and reliable sales, which can stretch for several months. This year's Year-End-Sale, from November 10 to January 1, is just one doozy of an example.

3. London
Getting around: 6 Value: 6 Variety: 10 Experience: 9 Total: 31
London prices can destroy your will to live. And that's just the cab fare to get to the shopping areas.
But get over the sticker shock and you'll probably agree with its Globe Shopper Index ranking as top European shopping city and its Donegar Group nod as the world's top fashion shopping destination.
The Globe Shopper City Index notes that London outstrips all the other European cities in both the quantity of shops and availability of international and local brands.
London shopping at its best is bold, eclectic and international. Case in point: department store Liberty.
Liberty may have a Tudor-style exterior and fireplaces, but its stock is contemporary and cool, encompassing in-house designer stationary, clever kitchen accessories to upstage your neighbors and clothes from a select pool of local and international designers.
Of course, you might end up with a £245 (US$390) Mathieu Challières Mini Volière Bird Cage Table Lamp, but that's the black magic of a wonderful shop -- it inspires you to buy things you never knew existed.
Whip out the plastic at:
Liberty, Great Marlborough Street, London, +44 20 7734 1234; open Monday-Saturday 10 a.m.-8 p.m., Sunday noon-6 p.m.

The ultimate Tokyo shopping experience is the department store. Walk into one and you'll be met like a royal.
Global chain Isetan has its mammoth flagship store in Shinjuku, eight separate buildings stretched along two blocks. Isetan has English, Chinese and Korean-speaking staff and a personalized interpretation service, as well as shopping consultants who will advise you on everything from shoes to fish, all available through reservation (+81 3 3225 2514).
A foodie heaven, the basement has dainty Japanese bento boxes as well as French pastries and macaroons. When shopping for clothes you can take a break from the international luxury brands on stock to try on some kimonos.
Tokyo's shopping is also surprisingly affordable, according to the Globe Shopper City Index, with Asia's fourth-cheapest shopping, and the cheapest average price for a Canon EOS 600D body.
