The piece is made of 100% cotton, a natural fabric that feels soft against the skin and allows air to circulate, making it a comfortable choice for summer. Its lightweight, thin construction suits the retro, relaxed aesthetic of the design, while the cotton lining adds a smooth interior layer that helps the piece sit comfortably during casual, everyday wear. Together, the cotton body and cotton lining support the easy, lazy-style look and the fitted silhouette, ideal for campus, citywalk, daily, and countryside settings.
