Gomez rocked a sparkling crystal-covered gown for her first red carpet look.

Selena Gomez brought double the glamour to the red carpet during her inaugural Rare Impact Fund Benefit Supporting Youth Mental Health on Wednesday night. The multi-talented star effortlessly switched from a dazzling silver gown to a playful floral minidress before making yet another stunning transformation into a chic black velvet ensemble once inside.

The 31-year-old Rare Beauty founder made her grand entrance in a custom Valentino halter gown adorned with glistening crystals. The gown featured an elegant rosette at the neckline and a sweeping train, exuding sheer red carpet opulence. Gomez also debuted a fresh, shorter haircut at the event, sporting her shoulder-length locks in a sleek, straight bob. She completed her look with dazzling Messika chandelier earrings that added an extra touch of sparkle.

While she kept the same earrings, Gomez traded her silver gown for a fun and flirty floral minidress. This delightful outfit was paired with strappy metallic heels, adding a touch of playfulness to her ensemble.
