Startup Idea : Storetracer

My idea greatly works for people who are greedy for clothes and who are particular about stuff like type of dress,color ,size ,material used.Most people must be fed up roaming and wasting time in shopping particularly women and in big cities it takes a lot of time in travelling . Though we have lots of online shopping sites the problem is we dont know whether dress suits us or not unless we make a trial and also we are not sure about the material used unless we personally check it.So my idea is to create an app or website that takes all the details like type of dress you want,color ,price range and it will give you the list of shops along with their address who are having similar kind of dress and we can directly go and grab the dress we like and can save a lot of time.please suggest me if there is an app already existing.
