just wanted to make sure if these were ok i saw some people last year who didnt have shirts on and a couple of my costumes require not shirt so i just wanted to check if i would get in trouble
I'm no authority, but Last year I was one of the people cosplaying without a shirt. (black and leopard neko's) Anyway, I never had a problem. I mean, only do as far as your comfort level will allow, if you're uncomfortable, you'll look uncomfortable, and that projects to others.
Other than that, make sure it looks good, by not wearing a shirt, you're saying your body IS the cosplay. Wish you the best, I may be doing This year's Hypno costume in a semi-undressed fashion.
Pushing the envelope for the win.
