My physique tells people what the hell I do.
I always wear a tank top, but I tan as much as I can. If I'm broken out I use Dermablend, it's makeup that was meant to cover tattoos. Very opaque and heavy and meant to be used on the body, not the face. Waterproof and will last a workout. If you look close you can see my skin is not perfect but it doesn't look nasty. Guys could probably use it too; people would just think it was some kind of self tanner.
