Use the charts below to determine your size. If one of your body measurements is on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit.

    Youth sizing has been researched and developed based on British Standards. Sizing has been based on an average age with height provided as a secondary reference.

  • Leg Length:

    • Serious Stuff has worked to provide a standard-length leg (32”) for adult sizes XS-3XL.
    • Long leg option is available in selected styles. Please call Serious Stuff office to request this option.
    • Short and Long leg options are available when ordering bespoke from the factory (Factory orders require a minimum order of 10 pieces and incur a 8 week lead time).
    • Short and long fit bottoms are 2”/5cm shorter and longer than the standard regular leg.


    Please Note: Serious Stuff have arranged the above sizing guides to help you find the best fit. If you need further help please don’t hesitate to contact us. Serious Stuff also offers a personal fitting service.
