The color "sheer nude" is really a ballet pink cream color, that might as well be white.  I couldn't wear them when I want a nude/skin color underlay, the color is too light and would be a visible variance from my skin tone.

That said, they fit as expected.  I'm a size 8-10 in jeans, and the Medium fits well.  Also, note, you can buy them at a discount on the Jockey website.  Since they ship directly from Jockey there's not really a reason to buy them here.
