This is a style from JC Penney’s that they sell at a lower price point all the time and rarely put on sale. It has been available for many years, then was dropped from their line for a while, then recently brought back due to demand from customers. The upper part of the cup and center gore are non-stretch lace. The straps are non-stretch except for a short section in back and adjust in front. Sorry the pictures are so poor- black gives me a hard time.
