Yes.

Absolutely not. If you watched the video, the end result was a garment that was not stuck to the wearer. The straps were independent from the shoulders. The rest of it flowed and fluttered like real fabric, and not like the typical "spray on dress" we've seen before. It's not a coating once finished. It's a separate thing.

Notice how the fabric didn't cling to her inner legs, but bridged that gap instead.

Now I agree that I'd like to see how durable this thing is once it's been washed. I'll accept whatever wash method is standard for a fancy dress. That is: if it can't be tossed into a normal washing machine, but can be handwashed with Woolite in the sink, then that's good enough for me.
