Virtual mirror to replace changing rooms

Great Idea!!!! I was just thinking of a product like this. Not just for the Retail Stores, but for the home aswell. I believe you are on the right track. Just need to add some more AI to it. The possibility with this is endless.

Or more accurately (for women's clothing, as illustrated), rack" size (can and usually does) varies, as do other parts too

How does this mirror in the slightest tell us how the outfit will look on us? This shows us what it would look like if we held the dress up in front of us, which we can do with the mirrors already in most clothing shops. We're all shaped differently, and we have to actually put the fabric around our bodies to see if it will hang correctly, if the size is right (no matter what size you are, different brands size their clothing differently), etc. This is a gimmick, not a useful item.
