If you prefer non-yonex, check: http://www.e-badmintonusa.com/Clothing.html I got quite a few from them. Very nice quality vs. price ratio. For yonex, check www.badmintonalley.com or www.badminton.net, but kinda limited in varieties. Also, there are a few reputable ebay seller for Yonex shirt. However, buying from ebay usually means higher risk, though.
