T-Shirts Under the Uniform

[golfdesigner]

Had a couple of games [underclass] this past weekend, there were many players with T-Shirts under the uniforms, because it was a Frosh game, we didn't really make a point of the color contrast. The uniforms were green, the T-shirts white, my partner felt that white under the green uniform was okay, but had a problem with the sleeveless T-shirts [also white] and felt that those sleeve-less shirts were "illegal". I guess I would have gone the route of the T-Shirt not acceptable, while the sleeve-less, with nothing showing from under the uniform was okay.

Just want to get some ideas and get on firm ground if this comes up at higher level.
