What can I say except that these are absolutely perfect!  I must own a dozen 'racerback' style bras, but all of them still show when worn with racerback style shirts. I understand that it's in style to show your bra, but that isn't for me. I don't want my bra to show through my clothes. I took a chance on these and I'm not disappointed.  I am 5'3 128 pounds and I normally wear a size small, sometimes medium tops. My bra size is 32 DD or 34 D.  I was worried about this one size fitting but it turns out it fits fine and they're quite comfortable. The straps are adjustable so you can increase your support if you need it. Because it's a stretchy material I honestly do think these would fit women who typically wear size small to large.  The material is very soft and overall this bra is comfortable enough to sleep in. My only complaint is that the light pink one came with a stain on it. I just threw them all in the wash which is what I would do with new clothing anyway. I'm hopefully that stain will come out. Please see my photos including one with a racerback style tank top. I'm wearing the green bra underneath my blue tank and you can't see the bra That's exactly how a racerback bra should fit.  I definitely recommend these.
