Each product page features a detailed size guide. We recommend measuring a t-shirt you already love and comparing those dimensions to our chart for the perfect fit.

We offer a 30-day return policy for all unworn and unwashed items. If you are not satisfied with your fit or color, you can initiate an exchange or return through our online portal.
How long will it take to receive my order?
Standard shipping typically takes 3-5 business days within the continental US. International shipping times vary by location but generally take 7-14 business days.

To minimize shrinkage, we recommend washing your ONNO shirts in cold water and hanging them to dry. If using a dryer, please use a low-heat setting.
