Contour your shape with this Perfection Primer bra from Wacoal. Constructed using marshmallow-soft foam cups, this piece delivers a comfortable feel against the skin & a natural shape with a little boost.. A clean turned neckline sits smoothly against the bust, while brushed, low-stretch fully adjustable straps anchor the bra in place without digging in. A J-hook strap adjustment allows this bra to be worn as a racer back.
