We get a bit giddy every time we think about summer and all of the flip-flops we'll be sporting. Maybe we're too casual, but we believe there is a perfect pair of flip-flops for every occasion. And these Flipped Notecards ($12 for 8) further prove that point! Jot a note on one of these bright cards to invite a buddy for a beach date, to say thanks for the killer birthday present, or to send a pick-me-up to a downcast friend. Your Havaianas can't do that.
