I'm not going to say this is my first design and beg for you guys to go easy for two reasons: 1. You won't anyway. 2. That kinda defeats the purpose of the site.
So, I'd say the design is pretty self explanatory. Pretty much any light colour t-shirt would work. Center placement, which could obviously be moved if the ladies were worried about their lady parts.
Other placement suggestions? Lower right corner or upper right corner.
