ICYMI: Hailey Bieber Just Wore a Barely-There Slip Dress to the World Cup After-Party

Justin Bieber headlined the 2026 World Cup Final Halftime Show yesterday, but its after-party was defined by another member of the Bieber family. Hailey Bieber was spotted accompanying her husband to dinner at The Corner Store in New York City and later to the performer's Skylrk after-party at The Twenty Two, where the couple and a slew of their closest friends celebrated Spain's dominant victory earlier in the day. For the occasion, Hailey pulled out one of her best looks of the year, and that's saying something given the sheer volume of save-worthy ensembles she's already debuted. Specifically, she broke out a vintage Christian Dior slip dress by John Galliano from the F/W 05 collection, pairing the lingerie-inspired burgundy number with sky-high thong sandals by The Row (the sold-out Sacha Sandals, to be exact) and a croc-embossed clutch from the same brand.

Hailey's dress style is one of her go-tos and has been for years, though she usually opts for Saint Laurent styles given her role as an ambassador for the brand. At the house's F/W 26 show in Paris, she wore a lace-trim teddy styled with heeled orange satin sandals and a color-blocked windbreaker on top. To celebrate the release of Justin's new album, Swag II, in September 2025, she chose a lace-trim black minidress by Saint Laurent, styling it with rhinestone-and-satin sandals and the brand's Icare Hobo Bag. She wears slip dresses well, so it makes perfect sense why they've become a constant in her ever-evolving wardrobe.

Hailey wasn't even the only A-lister who donned the dress style to Skylrk's after-party on Sunday evening. Tate McRae, too, wore a lingerie-like slip to the event, choosing a black version by Saint Laurent and styling it with Chanel metallic heels in gold. The look came after the singer wore an all-white ensemble to the actual match, pairing a cropped polo with low-rise jeans. She posted a video of Justin performing at the game, attaching a goat emoji on top. Naturally, she celebrated alongside the Biebers later on that night.
