Say goodbye to summer (or rather, hello to S.F.'s Indian summer) with Nida Boutique's blowout summer sale, which goes into effect starting now! Today through Sunday, September 18, it's last call for dozens upon dozens of items in the shop, including pieces by Opening Ceremony, Isabel Marant, and Melissa Shoes, which will all be marked down a whopping 80%. And, while you're there, we suggest taking a look at brand-spankin'-new fall shipments from Carven, Vanessa Bruno, Paul & Joe Sister, and the like. Ready, set, score!
