DIVE IN: Never mind the fact that today’s forecast calls for a high of 39 degrees. And never mind the fact that your muffin top grew love handles over the Christmas holiday. At Neiman Marcus, it’s swimwear time again, and the new 2010 collection will either send you under the covers to hibernate ‘til spring or provide you with bikini-clad motivation for your New Year’s resolution. We’re leaning toward the latter, as this chevron-print number by Milly ($188) would look darn cute in the hot tub. Even if it’s snowing. GET IT: Shop online at NeimanMarcus.com.
