Underwear is the part of your wardrobe closest to your body, so materials play a big role here. Look for slim boxers made from pima and Egyptian cotton, which provide good base layers without bunching up. The body line on Gap's boxers is cut with comfort in mind and only moves when you do. On your upper body, Splendid Mills V-necks start with a silky blend of Supima cotton and MicroModal, taking the notion of the perfect tee to a new level. [Socks by Lacoste, $14]
