An invitation to play with proportions, we kept the fit of this tee boxy and not-quite-oversized with wide sleeves and a squared shoulder seam. For fabric, we reached for our heavyweight cotton, a rugged-yet-soft choice that's perfect as a top on cooler days or used as an extra layer once the sun goes down. Boxy Fit: A relaxed and easy fit through shoulders, chest, and waist. Crew neck. Straight hem.
