This strapless, seamless piece is built for a smooth, breathable feel against the skin, with a cup lining made of 100% Polyester. The side wing lining and cup support are made of 50.6% Nylon and 49.4% Spandex, while the Style B side wing lining is 63% Nylon and 37% Spandex, giving the side areas a flexible, close fit. The cup padding is thin, ranging from 0.1 cm at its thinnest to 0.7 cm at its thickest, and the fabric is a lightweight 90 g with a 10D finish. The breathable cup structure and cooling finish suit the seamless, nude, small-bust strapless design, making the piece suitable for warm-weather layering and everyday wear under strapless or open necklines.
