We all know about the benefits of linen pants in the summertime, but for some reason many of us don't have any linen tops. Change all that with the Pacific Linen Shirt from Guess ($70). It features a button down front with chest patch pockets and button down epaulets on the shoulders. It's got military looks and a laid back attitude, and it comes in a dark olive — if thin white shirts scare you, that is.
