| Category | Runs | Shape | Length | Size advice | Confidence |
|---|---|---|---|---|---|
| Hoodies & sweatshirts | slightly large | most current ASOS Design hoodies are cut oversized with dropped shoulders and a wide body | regular to slightly long, with some cropped and some longline options | Stick to your true size in the oversized styles — sizing up often produces a very exaggerated fit. | medium |
| Shirts & overshirts | slightly small | slim and muscle fits sit very close through chest and arms; regular and relaxed fits are far more forgiving | regular, with slim styles sometimes reported as short in the sleeve for taller wearers | Size up one if you are between sizes or broader through the chest, especially in the slim and muscle fits. | medium |
| Trousers & pants | mixed | ranges from skinny and tapered smart trousers to genuinely wide, pleated relaxed cuts | inseam options are limited, so shorter wearers often report extra length | Check the leg opening and rise in the measurements before ordering, as the same waist size fits very differently across cuts. | medium |
| Jeans & denim | slightly small | waist sizing is often reported as tight to the label, with slim and skinny fits the closest cut | regular, though stretch denim tends to relax and lengthen with wear | Consider going up a waist size in rigid or non-stretch pairs; stretch denim usually works true to size. | medium |
| Jackets | mixed | tailored and biker styles run slim and shoulder-tight, while puffer and overshirt styles are cut roomy | regular; oversized and longline versions clearly longer | Size up in slim tailored or leather-look jackets if you want to layer, and stay true to size in the oversized outerwear. | medium |
| T-shirts & graphic tees | mixed | standard-fit tees read slim and close, while the oversized/relaxed line is deliberately boxy and dropped-shoulder | regular on standard fits; longline and oversized versions sit lower on the hip | Take your usual size in the oversized line and consider sizing up in the standard slim tees if you dislike a clingy fit. | medium |
