Threadfinder is a clothing comparison and recommendation engine. Any fashion recommendation service requires two key components: style and functionality. Many clothing comparison sites have functionality (that is, they compare clothes and help you find low prices) but don't have style.
Threadfinder is different. After 4 years of running one of the world's biggest fashion consultancies and personal styling services (http://agoodman.com.au), I built Threadfinder as a way of automating my skills as a stylist and ensuring that users get the coolest and most fashionable clothes they can.
It uses crowdsourcing as well as a learning algorithm which gets a sense of your taste in clothing and can recommend you new products to buy.
A live demo is available at http://threadfinder.net . We currently have 600 alpha users.
