Hailey’s Dior slip dress

Hailey Bieber spent Coachella weekend one in a 1990s Christian Dior slip dress, adding a vintage designer piece to the festival’s celebrity street-style mix. (vogue.com) Vogue published the look on April 12 and described the dress as a silky 1990s Dior slip with a standout color combination. The appearance came during Coachella’s first weekend, which runs April 10 to 12 in Indio, California. (vogue.com) (coachellavalley.com) Coachella has long functioned as both a music festival and a fashion stage, and the 2026 event is the festival’s 25th edition. Goldenvoice scheduled this year’s two weekends for April 10 to 12 and April 17 to 19 at the Empire Polo Club. (goldenvoice.com) (coachellavalley.com) A vintage slip dress carries a different message than the boho basics that defined earlier Coachella eras. Vogue framed Bieber’s outfit as part of a weekend-one street-style lineup that leaned on archival fashion and specific color styling, not just fringe and denim. (vogue.com) The Dior label matters here because 1990s and early-2000s pieces from the house, especially from the John Galliano era, remain a major part of the resale and collector market. Vintage dealers continue to market Christian Dior by John Galliano dresses from that period as collectible archive pieces. (vintagevonwerth.de) (resurrectionvintage.com) That makes Bieber’s outfit more than a festival dress change. It places a rare older runway-era house piece in one of pop culture’s most photographed April settings, where celebrity looks can move resale demand and shape the next round of festival dressing. (vogue.com) (goldenvoice.com) Bieber was not at a small niche event. Coachella’s 2026 lineup includes Sabrina Carpenter, Justin Bieber, and Karol G as headliners, keeping the audience for offstage fashion nearly as large as the audience for the performances themselves. (coachellavalley.com) (usatoday.com) The result is a familiar Coachella equation with a sharper luxury edge: one celebrity, one archival Dior slip, and one weekend built to turn a single outfit into a reference point before weekend two begins.
