I absolutely love these tanktops!  This is my second one I've purchased.  I've never had a flat stomach but these tanktops really help to smooth out all the way around and really flatter the waistline.  I feel as though they are true to size, although they seem to look much smaller than the regular shirts I wear, but that's so it holds everything in!  Love the length, love the fabric, love everything about them!!  I will definitely be purchasing more!!
