Digging your car out of the gray sludge left behind by the snowplow has you fondly remembering those swampy, 112 degree days of summer. Drop the shovel, bundle up, and go check out Thayer. The New York-based line offers a silk spring collection worth hiding under your parka until the sun comes out. We love the short, strapless yellow number flecked with gray and with a swath of fabric draped down one side. If you need full coverage, the gray maxi accented at the bust with coral and green will fit the bill. A backless, feather-print sundress gets an unexpected twist with crisscrossing ruffled straps. Just remember to pick up the rock salt on your way back home. Available at Arcadia, 819 North Second Street (215-667-8099 or arcadiaboutique.com).
