Raglan: Billy Reid's Sweater

This cozy layer by Billy Reid has the look of a sweater (or finely knit sweatshirt) and the weight of a cotton-blend t-shirt. It's soft, comfortable, and thin, making it a perfect choice for evenings on the porch after a full day in the sun. If you're headed out of town, especially to the beach, toss it into your weekend duffle in case chilly nights sneak up on you. [$135, billyreid.com]
