Size Guide


All of our t-shirts have a relaxed fit and our sweatshirts have a medium fit. If you want them to be oversized, we recommend going a size up.
We work with two different styles of sweatshirts and t-shirts: Women's and unisex. Make sure you check the right chart to find your size.
Any questions about size and fit please contact us at info@byisla.com.
Note: measurements are in cm.
