I have a simple, classic pair of J. Crew gladiator sandals (just like the ones pictured above) that I bought a few summers ago, and I've worn them into the ground. To say that they're versatile would be an understatement. There isn't a piece of summer wear that they don't go with, from a sundress to shorts to cropped jeans--and they work around the clock. But I also love the fact that they are neither too clunky nor too Roman Coliseum-authentic (i.e., they signal "I am feeling relaxed" more than "I am ready for battle"). Most incredibly, they're eight bucks(!), and they'll look great with...
