Veronica Brett pop-up

539 W 23rd St between Tenth and Eleventh Aves. Subway: C, E to 23rd St. After being frustrated by how swimwear fit her postmastectomy body, New Yorker Veronica Brett started designing sexy suits for breast cancer survivors and women who have had risk-reducing mastectomies. At this one-day temporary shop, you’ll find halter one-pieces ($225) and convertible bandeau suits ($240) with matching sarongs ($75). If you want to show some skin, keep a lookout for one-shoulder bikini tops with matching boy shorts ($205 for both). Ten percent of all proceeds benefit Young Survival Coalition (youngsurvival.org), a local organization devoted to young women diagnosed with breast cancer.
