Well, I don't really feel any need to look nice sitting around a pool, so a red shirt with 'GUARD' on the back works fine for me ^^ I rather like t-shirts, although I've started layering them with open dress-shirts and such, as my school is freezing. Sleeveless shirts are good too, mostly because I actually have arm muscle, and it's visible in sleeveless shirts, which creeps my guy friends out because it reminds them I could beat them up if I wanted to.

And considering my favorite color is purple, there will most definately be a purple shirt somewhere. And then I can wear it to Sakuracon, and annoy Ari XD
