Doctor says you're not getting enough butter. We can help. The Smooth Stripe Tee is made of our famous Butterknit, a fabric so soft and richly satisfying that we almost included nutritional facts for it. The clean and modern striping provide a nice wake-up from plain solid, and the shirt is punctuated with a bias-angled lines across the pocket. Made of 100% organic cotton - specially sanded and washed.
