Selena Gomez [1] surprised Swifties on stage when she joined Taylor for a performance during the Reputation tour [2]. Selena sang "Hands to Myself" in Pasadena, California, matching Taylor's concert dress code [3] to a T. While Taylor hung by her side in thigh-high boots and an embellished moto jacket, Selena's full jumpsuit was covered in sequins. It's the type of throw-on-and-go look we might reach for when we're feeling a little extra and we're damn proud of it. Ahead, get an all-angles view of the iconic moment, then shop some similar numbers should you need a little going-out inspiration [4] this season.
