# Hailey Bieber's Vintage Dior Slip Keeps the Nightgown Trend Going > A burgundy Galliano era minidress from 2005, worn to a Soho after party, and a season that refuses to let lingerie dressing go. - Source: Star Life - Canonical URL: https://starlife.channel/article/hailey-biebers-vintage-dior-slip-keeps-the-nightgown-trend-going - Author: Iris Bellamy - Section: Red Carpet - Published: 2026-07-20T16:55:00.000Z - Updated: 2026-07-20T16:55:00.000Z - Tags: Hailey Bieber, Dior, Vintage, Trends --- Lingerie dressing has been declared finished several times this year and keeps refusing to go. Hailey Bieber's latest outing is the strongest argument yet that it is simply the shape of the season. Following her husband's World Cup final halftime performance, the couple were photographed in Soho on their way to a Skylrk after party. ## The dress The dress is a vintage Christian Dior minidress by John Galliano, from the label's autumn 2005 collection: burgundy floral jacquard cut as a slip, with lace running along the neckline and the hem. Her only additions were black thong kitten heels and a narrow pair of black sunglasses. The dress is twenty one years old and looks like it was cut for this summer. Sleepwear inspired dressing, which the internet has settled on calling nightiecore, has been one of the defining trends of the season, with lace trimmed slips and nightgown silhouettes turning up on runways and on people who have never been near one. ## The contrast is the couple's signature Justin Bieber changed into a white dotted Skylrk hoodie over a long green shirt with wide leg jeans and trainers, plus Logan Hollowell earrings. The pairing of her precise vintage tailoring against his oversized streetwear has been consistent for years and is now effectively a look in itself. The party drew a crowded guest list including Camila Cabello, Kaia Gerber, Tate McRae, Winnie Harlow, Teyana Taylor, and Jalen Brunson. ## A busy stretch The outing came days after she unveiled a Gap denim collaboration built around her long standing preference for relaxed nineties jeans. Talking to Vogue about it, she said she had been closely involved across the shoot, the video, the storytelling, and the design, because she is past the stage of lending her name to something that is not a real collaboration. She added that she is specific to the point of being picky about how things fit and feel. On the evidence of a 2005 Dior slip worn without a single adjustment, that tracks. --- Originally published by Star Life.
