Fashion is in for the young ones in Thailand. And the stuff is AFFORDABLE.
Shoes, tops, pants, bathing suits, purses (a great line with the letter G on the front, great quality and cheap), belts, accessories, the list goes on. Great cuts for the clothing... $300 would fill up suitcases... and what would that get you at home... 1 of each.
Touristy stuff usually gets filed in closets... think about that before you spend
Remember... PHUKET is NOT the place to do any shopping.
Bangkok is usually the best bet...
except for the SUNDAY Market in Chiang Mai on Ratchnedamneon Rd starting at Tapae Gate
PS... when you're barganing... the best way to know you've just over bid and to stop right there is when they say.... "Mister, you give me more!" at that point... hold firm and you'll seal the deal.
have fun.. any specific advice ... feel free to pm me.. i might miss a question otherwise.
