A high percentage of women wear the wrong bra size, which isn’t surprising given how tricky the measurements can be—even before factoring in hormonal changes, weight fluctuations, or shifts in body shape over time—and the EverFlexing Underwire Bra is a first-of-its-kind innovation engineered to flex across six traditional sizes.

“As women, our bodies are ever flexing; even a change of just seven pounds can impact bra size,” said Miryha Fantegrossi, SVP of Merchandising and Design at Wacoal America, “Our EverFlexing bra adapts with you, instead of forcing you to fit into a static size.”

With four-wary-stretch fabric, a proprietary flexible underwire and a five-row stretch hook-and-eye closure, the EverFlexing Underwire Bra accommodates everything from hormonal shifts and pregnancy to menopause and the effects of weight loss medications.
