buying clothes on the internet is always a good idea because when you buy things on the internet you have allot of discount you know better then buying them in store off course what everybody is doing.
Buying on internet or with bitcoin would only be good if you have a website or a store from your own country because in that case you wont need to be worried about shipping and all, but if the site you are ordering something is international then the shipping fees would be quite high and that wont let you have any discounts at all, the discount you might get on the product will be wasted on shipping fees.
