Size is debatable. Tag says 36B, bra says 34B. Definitely seems small enough to be a 34. I can measure upon request. Color is purple. Much more than a T-shirt bra. With a cool-to-the-touch feel and high-shine look, our NEW Microfiber T-Shirt Bra features smooth, lightly padded cups, a sexy caged back, and an infinity-edge neckline that disappears under clothing. Lightly padded Underwire Bonded neckline Recycled microfiber fabric Rose gold-tone X logo charm at center front Adjustable plush-back logo elastic straps Caged back Rose gold-tone hardware Hook-and-eye back closure Body: 78% Recycled Nylon, 22% Elastane; Cup Lining: 100% Polyester
