Same LA skate-graphic era, mascot logo instead of diamond
What changes: More blog/media-driven, cut-and-sew leans slightly pricier
Brand profile
Founder-run Los Angeles skate and streetwear brand known for its diamond logo, Tiffany-blue graphics and skate hardware.
35 brands like Diamond Supply Co. like The Hundreds, Huf, Crooks & Castles →

Nick Tershay started out selling bolts, bearings and decks from a San Francisco apartment in 1998, and the brand still stocks hardware alongside tees, hoodies, caps and denim.
Most of the line is graphic-led: the diamond mark and a Tiffany-blue palette applied across t-shirts and hoodies at accessible streetwear prices.
The Nike SB "Tiffany" Dunk collaboration pulled the label into sneaker culture, and it has since sponsored pro skaters and licensed its name to outside products.
Overall fit
true to size
Most shoppers report Diamond Supply pieces fit close to standard US streetwear sizing, with a regular-to-slightly-boxy cut and occasional shrinkage on heavier cotton tees and fleece.
Tip: Take your usual US size, and consider one up if you want the looser skate silhouette or expect cotton shrinkage after hot washes.

By category
| Category | Runs | Shape | Size advice |
|---|---|---|---|
| Hoodies & sweatshirts | true to size | regular to relaxed, roomy through the body | Stick with your usual size unless you layer heavily underneath, in which case go up one. |
| Jeans & denim | true to size | straight to slim skate-friendly cut depending on model | Take your measured waist size and check the specific model, as fits range from slim to straight. |
| Jackets | slightly large | relaxed coach-jacket and workwear-style cuts | Consider your true size or one down if you prefer a trimmer fit, since outerwear is cut with layering room. |
| T-shirts & graphic tees | true to size | regular, mildly boxy chest with a straight body | Order your normal tee size; size up one if you want the modern oversized skate drape or wash hot. |
