Our shirts tend to fit in between a basic fit and a slim fit. Please note that the measurements we give in our size charts have a variance of +/- 1 cm. Size charts vary depending on the style of the shirt and the material it is made of (cotton, organic cotton, spandex, etc.). You can visit the product page for specific size details. If you have any question regarding the size charts, please email us at firstname.lastname@example.org, we'd get back to you shortly.
