Our button-up shirts come in sizes 2-18. To give you a reference, they are similar in sizing compared to J.Crew. If you wear a size 10 in J.Crew, you are likely a size 10 in Kirrin Finch. For those who are more familiar with men's XS-XL sizing, we would recommend that those who wear a men's XS are likely a 2 or a 4 in our shirts, depending on how you like to wear it.
There is approximately an inch difference between each size, so if you are unsure about your size, we think it really comes down to how you like to wear your shirts. For a looser fit, go with the size up, or if you like a more slim cut, go with the size down. Still unsure? Shoot us an e-mail and we are happy to answers more questions to help you pick out the right size.
