Hailey and cousin Ireland Baldwin, also a bridesmaid, were among the several guests who shared photos and videos of the wedding at the Upstate New York restaurant and farm Blue Hill at Stone Barns. Hailey wore a halter dress with a plunging neckline, paired with a black lace choker. Ireland was in a much lacier off-the-shoulder gown.
Though their lacy black gowns made them look like goth queens, the party was anything but somber.
Alaia changed out of her big tulle ball gown and into a simpler sheath, the better to get down with the raucous Baldwin clan.
In several Instagram Stories, the ladies jump, dance, and belt out lyrics to each other along with a live band as well as a DJ's playlist.
Hailey rapped and mimed one song to her mother, Kennya Baldwin.
She also joked, "Dad said me next ... NOT," in a selfie embracing her actor father.
We unfortunately only have a still shot of Hailey's speech at the wedding.
Another famous daughter at the wedding was 19-year-old model Sailor Brinkley Cook, daughter of Christie Brinkley, who showed off her impressive dance moves (and less impressive singing voice) in a red halter jumpsuit.
Actress Alona Tal, a friend of Alaia's, posted a couple of photos of herself at the wedding, writing, "So happy for this girl. She deserves the best and that's what she got!"
