My twin sister is currently working in Paris, spending the little downtime she has running around the city trying to nab this season's most coveted, already-sold-out-in-the-US shoe, the Chanel slingback, above. (I managed to snap up a pair while I was there a few weeks ago!) This toe- capped, mid-heeled shoe was featured in Chanel's Fall 2015 ready-to-wear show with nearly all of the 98 looks. So far, my sister hasn't had any luck in landing a pair of her own. I recommend she set her sights forward and buy the next must-have shoe, the resort-ready Gucci crossover sandal, below. Get them now while they last .
