Katie Open-Back Satin Gown

Essentials this cool are hard to come by—then again, you’d be hard-pressed to find a cooler duo than Georgia Cherrie and Paris Mitchell Temple, the New Zealanders at the helm, who previously ran an online shop that Vogue credited with “the best vintage.”

The 'Katie' is made from two-tone satin a delicate belt that complements the open-back bodice.
