Size Guide

Size Chart

All of our shirts are designed with a slightly looser fit, sitting just off the shoulders and away from the body. For a true to size fit you should take your usual size, for exaggerated oversized look we suggest sizing up one or two sizes.

Please email hello@withnothingunderneaths.com if you need any help with sizing or selecting the best style for a particular body type, we will be more than happy to help.

For specific shape measurements please refer to the guides below.
