All Marc Darcy suits are labelled in UK sizing, this is based on your chest and waist measurement in inches. For example, if your chest measures 40 inches then you should be a size 40. Similarly, if your waist measurement is 34 inches, you should be a 34 trouser. If you are between sizes, we recommend rounding up.

If given the option on the sizing choices, an "S" means the trouser has an inside leg length of 29 inches, and an "L" means the trouser has an inside leg length of 33 inches. For more help on measuring your size, see our handy guide here, and see all sizing guides here. How long are the trousers?All trousers marked "R" or not followed by a letter are a regular length of 31 inches for the inside leg length. Most trousers are only available in this regular length, however all trousers can be easily taken up, with about an inch of fabric that could also be let down. All Marc Darcy suits are cut to a slim fit, this creates a more tailored silhouette that is flattering on most body types. A slim fit follows the shape of the body, tapering at the ankle and slightly cinching the waist. This allows for a stylish look while still being comfortable and wearable. What if my suit doesn't fit me?
