This piece is made from 100% cotton, specifically 100% Xinjiang long-staple cotton, with a fabric weight of 300g. The long-staple cotton fibers are fine and resilient, giving the piece a substantial yet soft and skin-friendly feel that suits its retro, preppy, and casual aesthetic. The fabric is designed to hold up to repeated wear and machine washing while maintaining its shape, and the touch becomes even softer over time. The 300g weight provides a solid, structured drape that supports the relaxed, loose fit and the classic wide-stripe rugby look, making it ideal for everyday wear, campus life, studio commutes, city leisure, and weekend outings. The piece is suitable for spring and autumn, and its breathable, shape-retaining cotton construction fits a youthful, Ivy League-inspired style that works well for layering or wearing on its own.
