Its smooth, seamless cups help it stay invisible under clothing, which is a key feature for a t-shirt bra. The materials include polyester, nylon, and spandex blends that provide stretch and comfort but may require gentle hand washing to maintain quality.

The bra features an underwire for support, paired with a soft inner sling that helps shape the bust gently without added stiffness. It has convertible straps that can be worn straight or crossed in the back, adding versatility for different outfits, including low-back styles thanks to its deep U-shaped back design.
