I bought a mixed pack of blue, purple, black and "emerald" green. The green ended up being a super neon green, so I probably won't wear it, except maybe to sleep in.
Other than that, these tank tops are fantastic. I'm 5'9 and very hourglass shaped, and no camis ever fit me without rolling, sliding and constantly needing to be adjusted, but these do. If anything, they're probably a little too long for most people, but I love them. I can tuck them in and they'll stay that way, under skirts, jeans, whatever. I'll definitely be buying more.
