Vintage Gothic Western Shirt

An incredible unique shirt that has a western gothic/ dark academia/goth cottage core aesthetic style. Brand tag says Olive but there are no other tags showing size or fabric content. I estimate the shirt as S/M Shoulder 17", Armpit 18," Waist 18", Length 25", Arm inseam 16" Measurements are taken flat and are approximate. Please reach out w/questions or if you want more photos!
