What is the size of a successful boutique store?
The size of a successful boutique is most likely smaller than regular department stores as long as you have a heavy amount of stocks that can be shipped in quickly and easily so that your store never seems empty. If it is to be successful, it all really comes down to hwo much you advertise your store-not the size. The more you advertise, the more customers. But it is always important to have a quick and heavy stock inthe warehouse.
