The Elsa is like the Goldilocks of slip dresses: It’s not too loose, but not too tight. Made from an Italian scuba knit that offers weightless coverage with excellent stretch and recovery, it features a long hemline that looks great on all heights and lingerie snaps to keep your bra out of sight. Try layering it over a fitted turtleneck, like the Axam, or under the matching Shawn sweatshirt or Sierra shacket.
