These size charts correspond to the measurements of the garment, not your body. Don't know what size you'll like best? Grab your favourite jersey (or t-shirt), lay it flat, and measure across the garment. Double that measurement to get the circumference of your favourite t-shirt, and select the size that is closest to that from our size charts.
If you're still unsure of your size, feel free to email us at firstname.lastname@example.org or message us on social media and we'd be happy to help you out!
