if you ever need to know what to wear to the premiere of a Frozen movie, ask Selena Gomez. The 31-year-old “Lose You to Love Me” singer showed up to the premiere of Frozen 2 on Thursday in the most perfect outfit for the occasion: a white and blue dress with an icy blue cape adorned with sequins and feathers. The extravagant outfit is from the Marc Jacobs Fall runway, and Selena had a special guest on the red carpet twinning in a nearly identical outfit: her little sister, Gracie Teefey.

The adorable duo held hands and posed for sweet pictures at the premiere in Hollywood. Selena paired her dress with silver metallic heels and opted for braided pigtails to tie the themed look all together. See more photos of the sisters’ night out ahead, and take a look at the exact Marc Jacobs dresses they wore.
