Overview
- The couple were married in a private ceremony in Montecito on Saturday that Vogue said was attended by family and friends.
- Vogue accompanied Claudia Sulewski to a final Oscar de la Renta fitting in Beverly Hills where Billie Eilish joined by video and reacted emotionally to the bride's look.
- Sulewski wore multiple custom Oscar de la Renta looks, including an ivory ceremony gown with a fitted corset and a reception dress with a sculptural peplum made from recycled feathers and crystal pearls.
- The pair included their two rescued dogs, Peaches and Moose, in the procession with bows made from the bride's dress fabric and emphasized vegan and cruelty‑free design choices tied to Sulewski's beauty brand.
- Some outlets report that Billie Eilish led or officiated the ceremony and that several celebrities attended, but those specific claims rely on more limited or secondary sourcing.
