Bali Smooth U ultralight underwire bras Bundle of 2, Sz 40C One bra is deep turquoise, dark emerald green One bra is muted purple or lavender LIGHT AND SMOOTH SUPPORT Underwire support was never as light or as comfortable as in this One Smooth U® Ultra Light convertible bra. You'll appreciate the inner sling that comfortably enhances support and natural shaping without the extra bulk. The fabric is extra light and smooth, lying flat under your clothes with no bra lines. The two-ply, deep-U back offers even more smoothing as well as fashion flexibility with low-back clothes. Comfort-U® stay-in-place straps stay comfortably in place and convert from traditional to crisscross wear. A finishing touch is the sheer trim at the neckline, as smooth as it is pretty.
