By far the best, cheapest and coolest clothing store in Japan is Uniqlo. It’s kind of like the Gap or Old Navy but even cooler. I often like to go to buy T-shirts, as they have many really cool ones. The prices are really good too, and you can usually find sizes that fit western sized bodys. You can click the link and see their website and all of the cool stuff at Uniqlo . At the bottom you can click on the US or UK stores to see the English version.
