I first heard advertisements for body-scanning used to size clothing a number of years ago -- possibly even over a decade ago.  To my knowledge, such scanning has yet to catch on in a big way.  Frankly, I think that a lot of people just aren't comfortable with the idea of having their bodies scanned & the images/data shipped off for whoever to peruse it.  People also tend not to like airport security devices which allow security guards to "see" under clothing -- and being scanned for the purpose of fitting clothing falls into a similar vein.  Or at least the attitude towards the idea tends to be the same.

The same thing goes for the 'VR helmet' and 'VR glasses' designs of several years ago.  It just hasn't caught on, at least not yet.  According to predictions made at the time -- we should all be playing video games & even working while totally immersed in VR by now........well, that hasn't happened.  We'll see if it eventually does.

Some ideas sound better as concepts than they do as actualities.
