Hi, Timothy. Boys who wear leotards for class usually wear them inside their tights. Steve is right, though, in saying that the traditional top is a white tee-shirt. There are men's tops available, however, and one can make do with "muscle-tees" (fitted tee-shirts) available in many places, and in many different colors, beside white. (Best, perhaps, if you didn't have one with a rock group logo on the chest?)[/i]
