Tank is longer than I anticipated: it covers my butt almost entirely. Fitted at the bust (as mine is not small) and then the perfect amount of loose over my stomach. It is a bit fitted around my hips which can look weird over pants with a belt because it's too tight over the belt bulge. But mostly is fine. And I got a small, so medium would probably not be too tight on the hips, but I'd prefer it fitted in the top and wouldn't want it any longer either.
Only major complaint that lost a star is that the color is a bit of a dull red. In the picture I thought it looked brighter, but it is a warmer, softer red. I have cool undertones and don't really think any of the colors would suit me besides black and white. Even the navy looks like it would be soft and dull. Sivana, please make winter bright colors!
