Hailey Baldwin Wore a Plunging Maid of Honor Dress in Her Sister's Wedding

Taylor Swift wasn't the only stylish wedding attendee this weekend. Hailey Baldwin served as the maid of honor in her sister Alaia's wedding in Tarrytown, New York, on Saturday. Eschewing the typical pastel bridesmaid dress, she wore a striking black gown with a plunging neckline for the occasion. Alaia's other bridesmaids, including her cousin Ireland Baldwin, also wore black dresses, though slightly different versions. How gorgeous was this wedding?
