The jeans conform to your body with heat and wear, so we suggest going with a pair that is tight fitting initially. Trust us, if they button, they fit. All of the jeans are sized one at a time after production based on how they fit our size models, so expect slight variation in sizing. We run true to size, but if you are between sizes, we recommend sizing down. For men, go two sizes down from your normal size. If you are uncertain what size you would be, feel free to email us at firstname.lastname@example.org! Also please note that as our jeans are vintage, they will have slight imperfections such as distressing and markings. If this is a concern, please feel free to email us!
