Everything Is Denim in Diesel’s Pre-Fall 2025 Collection

Every piece in the collection — from jersey T-shirts and small tops to zip jackets and puffers — is treated to look like denim, if it’s not already employing the real deal. Across the line, Diesel introduces a new “fluid denim,” which forms spacious tailored jackets and pants, much of which are overdyed for a tethered look and drape nicely thanks to the textile’s lightweight build. Elsewhere, this “fluid denim” is cut into oversized shirts, which can easily be knotted, tucked or worn loose.

Psychedelic artwork helps facilitate the illusion of denim across knit tops, minidresses, scarf skirts, tracksuits, hoodies, T-shirts and tanks; while halterneck jumpsuits, panta-skirts and biker shorts all enlist the actual fabric. Meanwhile, distressed padded jackets trick the eye with a jacquard woven like torn denim, much like that which appeared on Diesel’s Spring 2025 runway in Milan this September. Knits are coated with a sheen to resemble jeans; jersey dresses boast trompe l’oeil denim prints, and classic footwear shapes — booties, loafers, sock-boots and sandals — are all covered in the brand’s favorite fabric.

“It’s a complete wardrobe with fabric innovations which proves that Diesel is denim, and that denim is Diesel,” Martens concluded.
