Product & Stock

Where can I find your size guide?

We never want to send you something that doesn't fit properly and understand that sizing can sometimes differ between brands.

Where is your size guide displayed?

Just click on the 'size guide' button on each product page to find out the measurements (which you can view in CM and Inches), size conversions and how to measure to make sure it fits perfectly.

The size guide is currently available for around 1000 brands, but if you can't see it on the product page, watch this space as we are looking into expanding the range shortly.

The size guides appear in different places depending on how you are viewing the site:

  • Desktop - Above the drop down for size selection
  • Mobile- Underneath 'add to bag'
  • App - Under the options below the 'add to bag' button

Can you recommend a size?

  • You'll also see our Fit Assistant on some product pages - keep an eye out for the blue circle near the 'size' drop down menu.
  • Our Fit Assistant will ask for information such as your height, age and weight to help you choose the right size when you order and will also look at your order history.
  • When you're logged in, you'll then see a size recommendation on some product pages.

Menswear sizing update
Have you heard? We’ve made our menswear collection even more inclusive! We've extended our sizing  across our main range to give you as much choice as possible, whatever your shape and size. You'll now be able to find your favourites in sizes 2XS to 4XL, and for those of you who are part of the Tall crew, from 2XS Long to 3XL Long. 

We’ve also reviewed our sizes to make sure they fit exactly as they should. So, we’ve removed 5XL and 6XL and sized up 3XL and 4XL to make them more accurate, and in line with other brands. If you used to buy 5XL, we’d recommend you now consider 3XL, and if you previously went for 6XL, we’d recommend considering 4XL.  Not sure of your perfect fit?  Make sure you check out our size guide.
