    Impi Sportswear has been designed specifically for teens and pre-teens, so you may find the "fit" a bit smaller. 

    While its best to measure as per our size guide page, here are some more ways to work out your preferred size remembering everyone likes a slightly different "fit".

      As a rough guide, our sizes are similar to the small ladies sizes 0-8. Bear in mind the bust/chest measurements will be slightly smaller for Impi sizes as the product is designed for teenagers. To show this slight variation we have placed a T in front of the relevant ladies size.

      Running shorts

      xs = size 0 age 8-10/11 years approx T0
      s = size 2 age 11-13/14 years approx T2
      m = size 4 age 14-15/16 years approx  T4
      l = size 6 age 15-16/17 years approx T6
      xl = size 8 age 16-18/small adult years approx T8


      Strappy crops

      xs not available in strappy
      s = size 2 age 8-10/11 years approx T2
      m = size 4 age 11-13/14 years approx T4
      l = size 6 age 14-15/16 years approx T6
      xl = size 8 age 16-17/18 years approx T8


      We know its not always easy to purchase online, so we have provided some of our model's measurements to help you work out which size will fit you best. Most of our running models prefer a snug fit for the shorts, so have opted for a smaller size in the running shorts and a size up in the strappy crop.

      Please do not hesitate to contact us if you need any further assistance in selecting the right size for you! We value your feedback and would love to know how our garments are fitting and where we can improve as we grow our business. Contact us at
