Cotton is perhaps a more casual and laid-back alternative to wool and linen. High-quality cotton offers a soft and smooth feel, better color retention, and—with proper care—a long lifespan. Cotton suits are especially popular in spring and summer. With the right cut and structure, they can also be highly versatile garments pairing well with other clothing and materials. Cotton doesn’t recover from wrinkles as well as wool, and its shape retention qualities are poorer. For this reason, a cotton suit may require more frequent ironing and careful storage.
