Ashley Graham Rocks Tiny White Bikini

Ashley Graham looks best when she brings it back to basics ... as in wearing a bikini.

Ashley did a photo shoot in Puerto Rico over the weekend showing off her new swimwear line SwimSuitsForAll ... and demonstrated her white bikini addition from her best angles.

A couple other bikini colors are already sold-out on her site ... here's hoping the winter campaign works.
