Jus curious

With underworks, I've heard that white tend to be bigger. Like, a small white and black would be slightly larger than one another.

Black is too dark, white turns to grey, I personally think they should start grey or come in skin tones.

My white one is half gray/blue/nasty so I'm going for black this time, I wear all dark clothes anyways so it won't show through anything I have.

Zombies I did hear that once before  do you know if it's a major difference? A medium in white is snug on me but I'm worried if I get a large in black it'll be wayyy too big :/

I have a small white trip top and a medium black tri top. They both seem to fit me as expected (white small is super snug, black medium is a bit looser), according to their measurements on their site. 

Then again their black small could be even more snug than the white small. *shrug* But the white one is pretty damn snug and fits as I would expect it too.

I've got a black one as I've seen a couple of really gross looking white ones and at least the black wont show it.  Also I wear a lot of black so it wont show through my clothes.

I like that my white one doesn't show under clothes, but it does look kind of gross now.  I think I'd prefer to have one of each.
