100% cotton. Ribbed mock neck. Below the elbow length sleeves. Jil Sander has a thing for experimenting with collars. This plain white tee isn’t your standard design, as it is made with a mock neck as opposed to the classic thin crew neck. A slightly relaxed, boxy fit helps it stand out even further from the solid T-shirts in your collection, with this particular design lending itself to dressier occasions. Don’t be afraid to rock it with slacks and a fresh pair of hard-bottoms for a more sophisticated yet contemporary look.
