21 brands like Muji like Uniqlo, Cos, Everlane →

It began in 1980 as a private label for Japan's Seiyu supermarkets, and the clothing still avoids logos and visible branding.
The apparel runs to undyed and unbleached cotton, boxy tees, wide-leg trousers and washable knitwear, with socks, underwear and tops the volume sellers.
Garments are sold within a full household range covering furniture, stationery and food, while MUJI Labo handles the seasonal unisex designs.
Overall fit
slightly small
Muji garments are cut in Japanese proportions, so while the silhouettes look boxy and relaxed, the actual grading tends to run about a size small for Western frames, with tight shoulders and short sleeves being the common complaint.
Tip: Most Western shoppers do best going one size up from their usual, particularly for tops and anything with a set shoulder seam.

By category
| Category | Runs | Shape | Size advice |
|---|---|---|---|
| Hoodies & sweatshirts | slightly small | straight and slightly boxy, not oversized despite the casual look | Go up a size for layering room and to avoid short sleeves. |
| Shirts & overshirts | runs small | regular to relaxed body but noticeably narrow across the chest, shoulders and armholes | Size up one, and consider two if you are broad-shouldered or have longer arms. |
| Trousers & pants | true to size | relaxed, tapered or wide-leg depending on model, generally forgiving in the seat and thigh | Take your usual waist but check the inseam, as lengths tend to run short. |
| Jeans & denim | slightly small | straight to relaxed with a mid rise; less stretch than the price suggests | Consider going up one waist size if you are between sizes, and expect a shorter inseam. |
| Jackets | runs small | clean and fairly narrow through the shoulders and chest, not a roomy outerwear cut | Size up one for layering over a sweater or hoodie. |
| T-shirts & graphic tees | slightly small | boxy with a fairly straight body and a wide neck opening on some styles | Size up one if you want normal length and room in the shoulders; stay true to size only if you like a cropped, boxy look. |

Muji is the apparel and lifestyle brand of Tokyo-based Ryohin Keikaku, launched in 1980 as a no-brand private label for Japan's Seiyu supermarkets; clothing arrived in 1981 and the first store, MUJI Aoyama, opened in 1983. Ryohin Keikaku became independent in 1989 and now runs stores worldwide. Clothing focuses on undyed and unbleached cotton, boxy tees, wide-leg trousers and washable knitwear, priced low and sold beside furniture, stationery and food. The US subsidiary filed Chapter 11 in 2020, restructuring around regional markets and e-commerce; MUJI Labo covers seasonal unisex designs.
