Anyone who lives along the California coast is intimately familiar with the seemingly impermeable grey layer of fog that creeps in overnight and lingers till mid-morning or so. This kind of weather calls for a light sweater, and since I hate being cold, I always have one in my bag (or car) at the ready. Randomly, I also love the way a sweater looks over a bathing suit. Inspiration: Caroline Bessette boating off chilly Martha's Vineyard with John Kennedy, Jr. I like to throw a loose-fitting cardigan not all the way buttoned up and over a bikini. Hence, I am always on the lookout for more light sweaters, and lately I've found a few that are not only fog and fall-proof but summer sexy, including these by Madewell, Equipment, J.Crew, Theory, and Townsen.
