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.

| Category | Runs | Shape | Length | Size advice | Confidence |
|---|---|---|---|---|---|
| Hoodies & sweatshirts | slightly small | straight and slightly boxy, not oversized despite the casual look | regular to slightly short in body and sleeve | Go up a size for layering room and to avoid short sleeves. | medium |
| Shirts & overshirts | runs small | regular to relaxed body but noticeably narrow across the chest, shoulders and armholes | regular, often shorter in the tail than Western shirts | Size up one, and consider two if you are broad-shouldered or have longer arms. | high |
| Trousers & pants | true to size | relaxed, tapered or wide-leg depending on model, generally forgiving in the seat and thigh | inseams cut short for Western heights; taller wearers often find them cropped | Take your usual waist but check the inseam, as lengths tend to run short. | medium |
| Jeans & denim | slightly small | straight to relaxed with a mid rise; less stretch than the price suggests | short to regular inseam, often ankle-length on taller wearers | Consider going up one waist size if you are between sizes, and expect a shorter inseam. | medium |
| Jackets | runs small | clean and fairly narrow through the shoulders and chest, not a roomy outerwear cut | regular to slightly short, with sleeves that run short on longer arms | Size up one for layering over a sweater or hoodie. | medium |
| T-shirts & graphic tees | slightly small | boxy with a fairly straight body and a wide neck opening on some styles | short to regular body, sleeves often hit mid-bicep | 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. | high |
Muji fits slightly small. Most Western shoppers do best going one size up from their usual, particularly for tops and anything with a set shoulder seam. 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.
