The answer is yes bitcoin is now a days used for each and every thing in life. As we know that it is very famous thats why big shopping centers in the Asia and Europe are accepting bitcoin for shopping and because of that they reserve good amount of bitcoin. In the future the owners of these shopping centers are good traders of this currency.
As far as I know bitcoi can already be used for online shoppings. Because there online shops across some countries that are now accepting bitcoin as a payment for such shoppings. We can all look forward that more and mote shops will accept bitcoin. That not only for clothes. But as well as every single thing.
