Is there a website which will determine what you will look like in a certain outfit, if you give it your measurements?

Sort of using your body as a template, then superimposing an outfit you may like online so you can see if it suits you?

Have you looked at Dressipi? If you find one that does what you want, can you let us know?

That's such a good idea surely it must exist?
