Setup: To ensure optimal comfort and support, adjust the shoulder straps to a comfortable tension – they should be snug but not dig into your shoulders. The adjustable criss-cross feature allows you to reconfigure the straps to suit different clothing styles, such as a racerback top. Compatibility: This specific Wonderbra T Shirt Wired Bra is designed for D+ cup sizes, offering tailored support and shaping for fuller busts. Its seamless design makes it compatible with virtually any top where a smooth silhouette is desired. Care: Proper care is crucial for maintaining the bra's shape and longevity. Hand washing in cool water with a mild detergent is recommended. Gently squeeze out excess water and air dry by laying flat or hanging. Avoid machine washing, harsh detergents, bleach, and tumble drying, as these can damage the foam cups, underwire, and fabric elasticity. > Info needed: Specific care label instructions should always be followed.
