Abigail Anderson, a close friend of Taylor Swift, opted for a dress by Reformation for her wedding rehearsal dinner. Swift, who has been friends with Anderson for over two decades, is also a known fan of the Los Angeles-based fashion label.

Anderson was seen heading to the rehearsal dinner at Madison Square Garden wearing a butter yellow slip dress from Reformation. The Lilibeth Silk Dress features a cowl neckline and a detachable sheer cape, and retails for $328. It is also available in powder blue, navy, and berry.

She accessorized the dress with a gold Cult Gaia clutch, strappy sandals, and a red lip. Anderson was accompanied by her husband, Charlie Berard, who wore a blue suit. Other attendees at the event included Gigi Hadid, Bradley Cooper, Jack Antonoff, Rachel Antonoff, and bridesmaid Selena Gomez, who wore a black lace dress.

Swift has frequently worn Reformation pieces, including dresses, cashmere items, and shoes, for over a decade. Most recently, she wore a floral dress from the brand, likely the Everett Linen Dress, when announcing her contribution to the "Toy Story 5" soundtrack. She has also been seen in the brand's Jadey Cashmere Oversized V-Neck Sweater and Waldena Block Heeled Mule.

Reformation is known for its "cool-girl" aesthetic and is a regular in Swift's street style choices.
