Luleh by Maidenform Camisole Liquid Shaper Style #33426. $44.

This is a very versatile bra camisole that can be worn as a layer top under those spring and summer tanks and tops. Includes a fully lined shelf bra. The fabric is undecorated and shows like a knit tee shirt or tank so it can be worn as a layer meant to be seen. Very comfortable, moves as you moves no binding, very light and free, great for the warmer months ahead. You almost feel as though you're not wearing any  bra at all.
