One way to keep cool during the summer heat is to wear a hat and this summer it is all about the straw fedora as seen above on Rihanna, Vanessa Minnillo, Jessica Alba, and Diane Kruger. This style of hat is universally flattering and I myself own a straw fedora from Banana Republic that I wear all of the time! I think it looks particularly great when paired with my rayban wayfarers.
