Where can I find your size guide?

We never want to send you something that doesn't fit properly, so we have size guides available on most of our product pages to help you find the perfect fit  first time!

Where is your size guide displayed?


Just click on the 'Size Guide' button on each product page, or check out our Women's and Men's size guides for measurements, fitting tips, washing tips – everything to make sure it fits perfectly and stays looking great.

The size guide is specific for most brands and appears in different places depending on which device you are using to shop:

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. 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, best matched to the information you've provided.

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.
