"Boxy", "oversized", "relaxed", "regular" and "slim" appear on almost every streetwear product page — but they describe very different shapes. Knowing the difference is the easiest way to get the look you want and avoid returns.
Boxy fit
A boxy fit is wide and square: the body is roomy, the shoulders are dropped and the length is slightly shorter than usual. It creates a clean, structured silhouette that looks modern on its own and pairs perfectly with wide-leg pants. Try the Heavyweight Boxy T-Shirt or the Vintage Wash Boxy Hoodie.
Oversized fit
Oversized is roomy everywhere — wider body, longer sleeves and more length. The shoulder seam sits well below your natural shoulder and the fabric drapes loosely. It's the most relaxed streetwear look and works best in heavyweight fabric that holds its shape. See the Oversized Drop Shoulder T-Shirt or the Oversized Fleece Hoodie.
Relaxed fit
Relaxed sits between regular and oversized: a little extra room through the chest and body without looking big. It's comfortable, easy to layer and a good choice if you want an easygoing look that still feels neat. Try the Quick-Dry Relaxed Fit T-Shirt.
Regular fit
A regular fit follows your body with standard room — the shoulder seam sits on your shoulder and the length covers the waistband. It's the classic, versatile option for everyday wear and layering under jackets. See the Regular Fit T-Shirt.
Slim fit
Slim fit sits close to the body through the chest and sleeves for a sharp, tailored look. It's ideal under overshirts, open shirts and denim jackets. Try the Heavyweight Slim Fit T-Shirt.
Quick comparison
- Slim: close to the body, sharp and tailored.
- Regular: standard room, classic everyday fit.
- Relaxed: a little extra room, easygoing.
- Boxy: wide, square and slightly shorter.
- Oversized: roomy everywhere, longer and loose.
Which size should you choose?
Boxy and oversized pieces are designed with extra room, so in most cases you should take your usual size and let the pattern do the work. Sizing up in a regular fit isn't the same: the sleeves get too long and the shoulders look sloppy. Always compare the chest and length in the Size Guide on the product page with a piece you already own. Read more in How to Choose the Right Oversized Hoodie Size.
How to balance your outfit
- Boxy or oversized top + straight or wide-leg bottoms for a classic streetwear silhouette.
- Slim or regular top + wide-leg or barrel-leg pants to let the bottoms stand out — see How to Style Wide-Leg & Barrel-Leg Sweatpants.
- If everything is oversized, add structure with chunky sneakers or a jacket.

FAQ
Is boxy the same as oversized?
No. Boxy is wide and square with a slightly shorter length, while oversized is roomy everywhere, including longer sleeves and body length.
Should I size up for an oversized look?
Not if the piece is already cut oversized — take your usual size. Sizing up a regular fit gives long sleeves and a sloppy shoulder rather than a true oversized shape.
What fit is best for a heavyweight T-shirt?
Boxy and oversized fits suit heavyweight cotton best, because the thick fabric holds the wide shape and drapes straight down.
What does "true to size" mean on ZELX products?
It means you should order your usual size to get the fit described on the product page — the boxy or oversized shape is already built into the pattern.
