Chantelle 2031 Hedona molded underwire bra. Seamless molded cups, unlined and unpadded, non-stretch. Pretty lace in center gore and top of cups. Made in France. Leotard straps with back adjust. Sells for $68.00 online. Some online sellers describe it as a minimizing bra, other don’t. It must have at least a little minimizing effect.
I am very impressed by the apparent quality of this bra, both the materials and construction. The straps are elastic but are quite firm; they would probably give the support of solid straps and the comfort of stretch.
