SIRPLUS is the innovative London label with its origins in using surplus fabrics to make a range of simple yet perfectly tailored essentials. Beginning with a market stall on Portobello Road in 2010, SIRPLUS has gone on to win plaudits worldwide for its stylish reimaginings of wardrobe basics. The SIRPLUS Nehru jacket and waistcoat are signature items, while the brand's boxer shorts are where it all began. Luxurious formal waistcoats are English made. T-shirts are in organic cotton. A label for our times.

SIRPLUS pieces all fit true to size. Each item in every SIRPLUS collection is tailored for the perfect fit, to your usual size. For formalwear and the label's renowned jackets and waistcoats, there's no need to deviate from your usual size. For casual pieces, consider going a size up for a more relaxed fit. Shirts can be ordered a size larger if they're to be worn as an over-shirt over a t-shirt, for example, and consider ordering two to find the perfect SIRPLUS fit for you. All SIRPLUS underwear and trousers are true to size, so you can order you usual size with confidence.

SIRPLUS points to consider:

  • Essential basics fit true to size
  • Try a shirt size larger for more relaxed fit
  • If in doubt, try two sizes to make sure
