Find Your Perfect Fit

At Union 22, we want to ensure you get the right fit every time. Our products are categorised into three main fit types to help you make the best choice:

  • Slim Fit – Designed for a tailored look. We recommend going up a size compared to your usual size for the best fit.

  • Regular Fit – A classic, true-to-size fit. Stick with your usual size.

  • Big Fit – Offers a more relaxed, oversized feel. We suggest sizing down for a more standard fit or keep as is for an oversized look.

Already Shopped With Us?

If you've purchased from Union 22 before, you may already know your sizes in the brands we stock. In that case, you can likely stick with the sizes you've previously ordered while following the fit guidelines provided for each product. However, if you're shopping with us for the first time or are unsure about sizing, we highly recommend using the chart below as a reference. Our sizing guide is designed to help you make the right choice and avoid the hassle of returns or exchanges. If you need further assistance, our team is always happy to help.
