Brittany Cartwright showed off her figure in the best way. Cartwright, 36, took to Instagram on Thursday, July 24, to share a number of sizzling swimsuit pics while celebrating Cupshe, one of her favorite brands, on their 10-year anniversary. In one shot, she looked fierce in a brown triangle bikini top, which she teamed with a mesh one-piece finished with a plunging neckline and thick straps. Cartwright then changed into a pink number while taking a dip in her pool. The design featured a delicate orange floral pattern, with a cutout over her bodice and lace-up detail.
