Using
  a system created by a company called Bodymetrics, it is now possible to try
  on clothes without actually wearing them. 
Combined
  with technology from Microsoft’s Kinect camera, the new virtual fitting
  system creates 3D replicas of
  customers that show not only customers’ body measurements but also their movements.
  Through their 3D versions, customers can see how a selection of clothes will
  look on them in real life. 
This
  technology could prove to be very useful to online shoppers. According to
  Bodymetrics CEO Suran Goonatilake, even though many people shop online, 90%
  of them still prefer to buy clothes in actual stores. With Bodymetrics’
  system, online shoppers can check if the clothes “fit” before buying them,
  just like in real-world stores.  In the
  future, similar systems could be used in shopping sites like Amazon or
  installed in Smart TVs, and people can enjoy convenient shopping anywhere, anytime. 
In
  the meantime, real-world stores Selfridges and New Look in the UK are already
  using this body-mapping system, and some US-based stores are also planning to
  adopt it by summer this year. However, Goonatilake will still not reveal
  which stores will avail it. 
But
  even if virtual fitting lets customers see how clothes look on them, simulating what the clothes feel like
  when worn may be the next big challenge
  for system developers.
