| Category | Runs | Shape | Length | Size advice | Confidence |
|---|---|---|---|---|---|
| Shirts & overshirts | slightly small | trim/slim through the body with a defined waist, higher armhole | regular tuckable length, sleeves cut on the longer side | Order your true neck size but expect a slim body — go up a size if you prefer a fuller cut or plan to wear it untucked and relaxed. | medium |
| Trousers & pants | slightly small | trim seat and thigh, tailored rise on the chinos and dress trousers | often supplied long and expected to be hemmed in-house | Take your measured waist and size up if you're muscular through the thigh; plan on hemming since inseams run long. | medium |
| Jeans & denim | true to size | slim-straight with a moderate rise | long inseam intended for hemming or cuffing | Stick with your usual waist; rigid denim may feel snug at first and relax with wear. | low |
| Jackets | slightly small | soft-shouldered, unstructured and close-cut through the chest and waist | shorter, contemporary jacket length with a higher armhole | Try your usual chest size first but be ready to go up one if you layer over knitwear — and budget for the alterations the shops expect. | medium |
| T-shirts & graphic tees | slightly small | slim to regular, close through the chest and sleeve | regular | Consider one size up if you want a relaxed drape rather than a fitted look. | low |
