The six-to-eight week trial, which launches tomorrow (March 1), lets customers create a 3D model of their bodies by either uploading two photos of themselves, or by entering their measurements and a photo of their face.
The fitting room will then suggest clothing sizes based on the details entered.
In what the retailer claims is a first, customers can then dress their personalised 3D bodies online in either a complete outfit or mix and match skirts, jackets, tops and shoes.
It will launch with 50 items, with a further 10 added each week throughout the trial. Customers can add the clothes they like to their Tesco basket.
Emily Shamma, director of Tesco clothing online, says: “This is a really exciting opportunity for online clothing retailers. We know the main reason people get nervous about buying clothes online is simply because they cannot try them on first.”
She adds that the virtual fitting room service could spark an uplift in revenue.
Shamma says: “Not only are there practical benefits to the F&F virtual fitting room service, but customers can have great fun putting together different outfits and trying out different hairstyles – all on a virtual version of themselves.”
Tesco developed the service in partnership with digital start-up Metail.
