The material is very stretchy and very thin. From the front it looked OK (except obv you must wear a nude bra), but from the back it showed every line and lump from my bra and how it pulled at my back. I'm not fat but I'm not skinny either (5'5" 140 w/ a smaller upper frame).From the back on the light colored shirt, I felt I looked like a stuffed sausage. If you're thin you will not have this problem, otherwise find a thicker, more forgiving shirt or try your luck with a darker color.
