The piece is made with a fabric of 65% nylon and 35% spandex, a combination that gives it a soft, stretchy feel and a seamless, side-smoothing finish suited to a seamless push-up style for small busts. The lining is 96% cotton and 4% spandex, adding a soft, breathable interior against the skin. The piece has a 0.8cm pad and a 1cm strap, with adjustable straps and a four-row, three-hook back closure. The fabric is lightweight and breathable, with a waffle-grid soft support structure and 3D breathable holes for air circulation. It is a four-season style with antibacterial properties that remain effective after 300 washes.
