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.
Just wait and i think soon in the future more onlineshops will accepts bitcoin as part of their payment method.
For now few online shops are accepting bitcoin but here in my area there is no shops accept bitcoin because bitcoin is not too popular in my country yet.
