I am not the target customer. However, I really want to show this idea off to a bunch of people and see what they think.
People want to look good and having an automated system that can give you a "once over" seems nifty. Yes, it sounds vapid and for insecure people, but people waste time on being anxious about how they present themselves.
Why is everyone saying this is for insecure people? I'm also not the target audience for this, but I don't think people who are concerned about the way they look are inherently insecure.
I am not insecure (I think !?!?) but it would be nifty to have Alexa tell me that "harshaw, those jeans you are wearing have a giant stain and you should get a clean pair out of the drawer".
