Startup Idea : What can I wear tonight?

Every woman knows how difficult is finding something that fits well, models are perfect, no matter what they wear, but reality is different, every woman has a different body, shape, weight and height, so my idea is to allow real woman to be the MODELS, building a social app where I can say Oh my God, I am going to Shard tonight, what can I wear?? and I can specify my weight, shape, height, preferred color and style, how much I want to spend and other woman with my same body can show me pictures of themselves of what they would wear, how much they spent, where they bought that stuff!
