There were just 19 looks presented, but the fall 2025 collection cemented Jacobs’s flair for dramatics. With echoes of Belle Époque grandeur and riffs on Victorian splendor, the designer presented both his own version of beauty and an act of provocation—all wrapped up in an enormous leg-of-mutton sleeve.

The fashion crowd was back at the New York Public Library on Monday night ahead of the Fourth of July holiday weekend to revel in Marc Jacobs latest collection of dreamlike Victorian beauties.

As is his custom, Mr. Jacobs ran a tight ship for his runway show Monday evening at the New York Public Library. Doors closed, guests settled in hushed expectation, and at 7:30 sharp the first model emerged in a lavender lace top with protrusive sleeves that fanned out around her like the petals of an Imperial poppy.
