I see that many online stores are rapidly introducing virtual 3D fitting. Is this hype or a tool that can really increase sales? Maybe some of the forum members have already tested it? Please share the details.

If it were just a hype, a lot of companies wouldn't spend their money on it, would they? I often buy clothes and shoes from online stores, so the AR feature is very convenient for me to try the item on myself and then not waste time to returning it. But as far as I know today, the use of virtual fitting for objects is in great demand by online furniture stores. Read discussions on this topic on reddit, there is a lot of useful stuff there.
