It's fine for a shop, but bad for something aimed at dressing people properly and teaching them how to do so themselves.
Unfortunately, due to the differences in sizing between manufacturers, you'd probably have to be commissioning your own products for this to work, but it would be very cool for an off-the-peg suit shop, medium-high end lifestyle catalog (Land's End, etc) or something similar.
You may need fitting guides to show people how particular pieces of clothing should fit (trouser crease should break just above the shoe, shoulders should fit without bulging or sagging...) For bonus points, produce them with several different models with different body sizes - for me, having a heavier guy modelling a suit and showing how well it can disguise a gut would be a major selling point :)
Shoes, speaking personally, would be a total non-starter online. I seem to have narrower heels than many; I'll routinely find myself searching styles to find the ones that fit me properly there rather than slipping, even if they're right elsewhere. I'm sure some others will be a little wide acrosss the toes and need just the right level of bulging across the front, or a different arch height that makes positioning of the insole's mound under the bridge or the tongue important for their comfort.
tl;dr: I can't always just buy a certain size and know that will be right. If your business model is dependent on that being possible, it won't work for me and I doubt I'm unique.
Perhaps what we just need is rapid prototyping for clothes: "I'd like one like this, but with a more generous waist". Like bespoke tailoring but cheap and quick.
Agreed. It's not something I've done very often, but (for example) when you notice that the same trousers in two different waist sizes has different leg lengths in spite of what the tickets say, it's worth checking another pair sometimes.
Short of inputting your detailed measurements, I wonder how a site can solve that.
I once tried comparing official clothing measurements from various vendors online and came to the conclusion that they were all lying. Short of 3D scanning or painstaking measurement by hand, there isn't an easy solution. It certainly seems like a problem ripe for the picking.
Wow, someone please come forward with the name of this startup. I need new shoes, and if this works I'm spreading the news to everyone I know.
They're just at demo stage at the moment. They eventually want to integrate this into your outlet's website.
Also sucks that for all my fits, it always showed an Asics product, a brand which I personally don't like as their fits / soles are the worst for me.

It would be really cool to hack a Kinect (or more likely, several Kinects) into doing something like that for clothing.
