Have you ever watched people shopping? Buying the clothes is part of the whole experience. Abstracting it away removes a big part of it. You buy trendy clothing in trendy stores so that people can see you buying there. Why do you think clothing stores have such big and attention grabbing bags? People want to be seen walking down the mall with the bag.

Also, validate by taking a laptop to a clothing store and standing in front of the fitting rooms. Have people use the system. Realize how different it is from reality. Adjust accordingly.
