The small white bra fits very small.  It would be great for an A or B cup.  Just beware if you are a C or D cup I would go with a bigger size. Returning this bra.  The construction seems to be nice. There is no padding, but I use the disposable nursing pads anyways.  I  was going to use as a sleeping bra.  so, not a terrible bra just sized really really small!
