This piece is made from 100% polyester, a fabric that feels soft against the skin and supports the breathable, skin-friendly comfort noted for this style. The material suits the casual, everyday aesthetic of the piece and works well as a slim-fit base layer for the autumn season, fitting neatly into a daily wardrobe and a modern, contrast-color look. The fabric has a regular thickness, giving the piece a comfortable presence for autumn layering without extra bulk. The round neckline and fine stitching are finished with attention to detail, and the short length pairs naturally with the slim fit for a clean, everyday silhouette.
