MAD ABOUT MOD: It just doesn't get much more groovy than this, does it? The Grimaldi geometric-print sheath dress ($139.50) by MICHAEL Michael Kors opens itself up to tons of styling options across the seasons. Try it with a long cardi and thick tights, or chunky open-toed booties when things start to warm up again. The cotton/spandex dress is lined, which means we vote that you can wear it now without having to wait for the first cherry blossoms to show up. GET IT: Bloomingdales.com, Tysons Corner or 5300 Western Ave., Chevy Chase, Md.
