I encountered a lot of clothes site or online shop from Facebook but I cannot seen clothes shop who accepts bitcoin in exchange of their product. Moreover in this time I cannot use my bitcoin in exchange of any goods or products. Because bitcoin value now was still growing up and I think it's good for all users.
as i personally never purchase clothes online or using bitcoin, but i am sure that there must be so much shops who may be selling clothes and they may be accepting bitcoin as payment method.
