Nightie dresses have moved beyond the bedroom to become a major fashion statement for late summer. Championed first on spring 2026 runways at Chloé, Victoria Beckham, and Miu Miu, the loose-fitting, ultra-feminine frocks have gained traction on street style and among celebrities including Kaia Gerber, Bella Hadid, and Olivia Rodrigo. The silhouettes have also appeared frequently outside Copenhagen Fashion Week among fashion industry attendees.
The dresses' appeal rests on their versatility and whimsical design details. Features such as puffed sleeves, broderie anglaise, ribbons, and lace give the granny-inspired pieces a layered foundation suitable for daytime styling. Fashion insiders have paired nightie dresses with ballet flats, shield sunglasses, and silk headscarves for the predominant It-girl look.
The garments function as transitional wardrobe pieces that adapt across seasons and occasions. They work with lightweight outerwear, knee-high boots, and structured bags for various styling approaches. Chloé's babydoll silhouette serves as a modern bohemian base, while Dôen's broderie anglaise mini has been styled with suede jackets and heeled thong sandals by Copenhagen's fashion set.
Longline maxi versions and slinky black slip styles add further styling options. Kaia Gerber, featured on Vogue's latest cover, has worn the black slip style with a Gucci Jackie 1961 bag and skinny Saint Laurent sunglasses. Gap's strappy nightie shift-dress option, styled by Vogue Shopping's market editor Minty Mellon with a black summer sweater and heeled flats, represents another popular approach to the trend.
