What to know about Diesel
Glenn Martens rewired the denim
Since 2020 the Belgian designer, who also heads Maison Margiela, has pushed Diesel toward treated and devoré denim, distressed washes, latex and heavy logo use.
Jeans first, everything else after
Denim is the core competency after 1978 in Molvena, but the label also runs underwear, fragrance, the 1DR bag with Oval D hardware, and Diesel Living homeware.
Big house behind the label
Diesel belongs to Renzo Rosso's OTB Group alongside Margiela, Marni and Jil Sander, and shows in Milan to thousands of public attendees rather than press only.

How Diesel fits
Overall fit
slightly small
Shoppers most often report Diesel running a touch small and slim in its core denim, tees and jackets due to Italian sizing, while the newer designer-led oversized and treated-denim pieces fit large by design.
Tip: Take your usual size in the oversized/logo pieces but consider going up one in slim denim, tees and tailored jackets.

By category
| Category | Runs | Shape | Size advice |
|---|---|---|---|
| Hoodies & sweatshirts | mixed | ranges from a trim classic fit to very oversized in the designer-led drops | Check the specific style, since the basics run slim while the statement hoodies are already oversized. |
| Shirts & overshirts | slightly small | slim European cut through the chest and sleeve | Go up a size if you are between sizes or broader through the shoulders. |
| Trousers & pants | true to size | regular to tapered, with utility and cargo detailing on many styles | Order your usual waist and expect to check the length. |
| Jeans & denim | slightly small | mostly slim to tapered in the core range, with intentionally baggy and distressed styles in the fashion line | Consider one waist size up in the slim and skinny fits, and stay true to size in the loose 1996/D-Macs style cuts. |
| Jackets | slightly small | cut close through the chest and shoulders, typical of Italian sizing | Size up if you plan to layer a hoodie or knit underneath. |
| T-shirts & graphic tees | slightly small | slim and body-close on classic logo tees, boxier on the current oversized graphic pieces | Size up one if you want a relaxed drape in the standard logo tees. |
