Does as advertised (no show through) but generally not supportive and the cups are too small.  The straps are literally some "ribbon" material .... ????  cuts into the skin and not elastic / not very adjustable.  The bottom band is very thin and doesn't hold the bra down well or comfortably.  I'm currently looking for something better ----- why can't they make a 'petals' type bra in a racer back for larger breasted women????!!!!  I'm 34C, but in a BAD bra I look very sloppy.  I hope this review helped you.  If you are a B or less this might be all you need.  My favorite is Bali Spa Closure Bra... but hey, everyone knows when I'm cold in that one --- so the hunt continues...
