It's refreshing to see someone validate their idea like this and asking why it won't work. Too many times I've seen start ups jump right in and go for broken without careful validation.

Ultimately, I would not use your product because it's rare I buy a whole outfit at once and I like to try on my clothes before I buy them. Usually when I buy clothes it's more of an impulse buy and planning a whole out fit would give me time to think about the purchase and by then the impulse is gone. These reasons seem to be shared with the 2 low 20's females I asked.
