Sorry if this is a stupid question but I'm clueless when it comes to clothes... Should one wear a white undershirt underneath a black collared shirt? It's not a really fancy shirt, just something from Banana Republic that my dad gave me because it's too big for him and I wanted to wear it tomorrow to school. I was thinking of putting on a black shirt under the black collared shirt but I think that would look a little weird, and the white undershirt with black collared shirt looks fine in the mirror to me, but again, I'm clueless on this subject.
