Each tie dye shirt is made to order and hand made with 100% Ringspun Cotton for a truly one of a kind shirt. PLEASE NOTE: When ordering we highly suggest sizing up from what you would normally wear. The shirts will shrink a little during the tie dye and drying process. All of our tie dye shirts are pre-rinsed, soda ash soaked, post dye washed with commercial synthrapol detergent and then dried on med to high heat.
