Building outfits is a big part of the clothes shopping experience and fashion retailers have been slow to exploit advances in 3D technology that allow the customer to visualise what an outfit might look like. Retailers have experimented with mood board or 2D outfit builder applications which go some way to helping the customer see what garments look like together and share with their social network for feedback. triMirror is a Canadian based technology company which has been beavering away for several years on a 3D virtual reality technology that allows customers to visualise an outfit on a particular model avatar in a specific setting. triMirror’s virtual fitting room uses the first real-time solution in the world that allows the try-on of real clothes on real-dimensioned and highly customisable avatar bodies, and which allows the user to see where the garment is tight or loose, where it juts out or sags down, and how it behaves when they move around in various ways. triMirror’s is the only product that applies dynamic clothing and streams a live video back to users live over the web. The system can be implemented online, in-store (with gesture control, avatars, or virtual mirrors), in a gaming environment, and on mobile platforms and customised to retailers’ specific needs. Conversions increase while costs of returns of ill-fitting clothes decrease.
