Apart from a throw-on-and-go dress, my favorite hot day hero is a white lace blouse. As you can see, it easily goes with anything from jeans to a swimsuit--and always looks sexy! Fortunately, this summer ushered in a bevy of beauties to choose from including the on-sale BA&SH top, above (expertly worn with a black bra underneath), this Mango, this organza Topshop, this one-shouldered Miguelina, and this Ulla Johnson.
