Taylor Swift isn't the only one who spent the weekend at a wedding. Hailey Baldwin, 20, attended her sister Alaia's as Maid of Honor, E! News reports. Their cousin Ireland Baldwin, 21, was a bridesmaid.

24-year-old Alaia, who is a model like her sister, got married to Andrew Aronow in New York on Saturday. For the occasion, Hailey wore a black halter dress, lacey black choker, and huge jeweled earrings with her hair tied back. All the bridesmaids dressed in black, and they held white flowers for photos. Meanwhile, Alaia wore a white pouffy dress. See photos here:
