Grace Gummer revives cerulean blue, echoing Devil Wears Prada legacy

Colleen Allen’s cerulean blue landed with real force on Grace Gummer because the set was built like a statement, not a backdrop. The Fall 2025 look paired an elongated coat with a funnel neck and cascading hook-and-eye closures over matching trousers, then stopped just short of excess with stark white pumps and only gold hoop earrings.

Gummer wore the ensemble at FX’s Love Story: John F. Kennedy Jr. & Carolyn Bessette For Your Consideration event at Metrograph in New York on April 29, 2026, where she joined Naomi Watts, Sarah Pidgeon, Paul Anthony Kelly and Constance Zimmer. The choice felt especially pointed after Gummer stepped out in a creamy Bottega Veneta matching set for the The Devil Wears Prada 2 premiere in New York, a softer palette that only sharpened the impact of this electric blue return.

The color memory is the whole game here. Meryl Streep’s Miranda Priestly gave cerulean its most famous fashion monologue in The Devil Wears Prada, which was released in the United States on June 30, 2006, name-checking 2002 collections by Oscar de la Renta and Yves Saint Laurent and explaining how the shade traveled through eight designers’ collections before arriving in department stores. Two decades later, that joke has mutated into a trend forecast. Cerulean blue is back in circulation for 2026, helped along by the promotional wake of The Devil Wears Prada 2 and by a crop of spring and summer collections that have put the shade back on the front row.

That resurgence is not happening in a vacuum. Cerulean and closely related blues have shown up in collections from Tory Burch, Ashlyn, Loewe, Tom Ford, Dior, Victoria Beckham and Colleen Allen, giving the color both runway credibility and a clear styling lane. It reads polished without the stiffness of navy, less predictable than cream or camel, and far more assertive than the safe neutrals that dominate so much occasion dressing. On Gummer, the effect was especially clean: high-contrast, minimal, and controlled.

Allen’s own Fall 2025 collection made cerulean one of its key colors, so the look had the feel of a deliberate designer signature rather than a trend-chasing borrow. But Gummer gave it an extra layer of meaning. In one appearance, she connected a family fashion memory, a movie reference that has outlived its punchline, and a shade that feels newly relevant because it offers exactly what fashion wants right now: polish with a little bite.
