Introducing Reformation x Alexa Chung, a 30-piece collection from your favorite style reference. Since she’s everyone’s muse, we asked her to design proper knits, tailored outerwear, and a few romantic pieces inspired by her own closet. Your turn. Somebody's fancy. The Radziwill Silk Dress is a strapless dress with a sweetheart neckline that features a knot detail. Sleek, refined, and sexy, if you need that. Please dry clean before returning!

Rent for $90/week. Original retail price: $398, 77% off retail.
