Bangkok may very well be one the best places to shop in the world. Thais go all out when it comes to shopping malls and markets. It's in Thailand that I came to understand that "shopping 'til you drop" is actually possible. With huge outdoor markets and multi-floor malls, it's hard to know where to start. Here are some suggestions of great things to buy and where to buy them in Bangkok. Not only do Thai women love to add trendy accessories to their outfits, it seems they also really like to look great under their clothes too! If you are a small to medium in US sizes, you can find all sorts of panties, lacy bras, and sexy lingerie. For more exotic options, check out Baiyoke Markets to find belly dancer outfits and Las Vegas style halter tops. Buy three or more to get a wholesale price at Baiyoke, or browse shopping malls for great deals. Chatuchak Market - Also known as J.J. Market, Chatuchak is Bangkok's local weekend market. With more than 13,000 stalls the market sells everything, but it's a particularly great place to look for cheap clothes. Here you'll find about 1,000 stalls that sell every type of clothing imaginable. From t-shirts to shorts, skirts to sweaters, jackets to pants, there's everything here. You can find professional clothing as well as traditional Thai clothing. There are also hundreds of very cool shops that sell one-of-a-kind clothing by young, local Thai designers.
Siam Square is the local university area and is flooded with university students at any time of the day and night. It's also a great shopping area for clothes as they cater to the price-range of college students, and also have the latest, hip, fashionable clothing at inexpensive prices. T shirts, skirts, shorts, spaghetti strap tops, jeans, shoes, everything is available here. Also, if you go into some of the little alley ways, you'll find lots of other stores that are designer stores (local young Thai designers) at very inexpensive prices. The only drawback to Siam Square is, because Thais are small and these stores cater to young people, the sizes are very small. If you're above a US size 10, you're not likely to find anything to fit you here unfortunately.
MBK Mall is one of the best places to buy cheap clothes in Bangkok. It's an enormous mall that has around 8 floors and all types of clothing are available here.  From brand names to local designers, you'll find any type of cheap clothing you want. On the next to top floor, you'll see traditional Thai clothing as well as t shirts, short, jeans, skirts, jackets etc. On the ground, first, second and third floors, there are tons of little boutique shops and larger shops that sell any kind of clothing imaginable. Also, on these floors, there are several inexpensive tailors that can make you a skirt, a women's suit, a man's work suit, shirts, ties, - anything you want and all very cheaply.
Don't forget, if you go to any of the market areas, you can and are expected to bargain, so prices will be even cheaper than first stated. The only places you cannot bargain are in the large department stores and the supermarkets. Even in the smaller shops, they will sometimes offer you a discount although, here, it's best not to try to bargain but only to be 'indecisive' about buying more than one item. Miraculously, a lot of the time, the price will come down if you look like you might buy two or more.
