Time was, wearing a bra in public was either the stuff of fantasy (vintage Maidenform ads) or a signal that the wearer is engaged in the oldest profession (as shown in the new HBO series “Deuce”,  about the porn industry in the 1970s). Now the bra is fully out from under, whether it’s delicate lingerie styles for evening or modest knitted versions for day. Shiny fabrics and elasticized edges give the piece a sporty spin. In real life, these pieces will be worn showing though openwork knits or sheer tops, peeking out under jackets, or layered on top of shirts and dresses. Of course, for customers who can carry the look, they will simply be worn as tops.
