Most interpretations of the Turing Test ignore the fact that the judge could in fact, simply be an idiot. There are three parties in the Turing Test. The AI, The Real Person, and The Judge. For AI to be indistinguishable, the AI could get more complex, but the Real Person could get simpler(twitter comments). The third option is that The Judge gets less discerning.

look at the engineering mess of a background, and the pixelation of the jersey white. but i didnt google image search dior ponytail and yes they do sell this wig ring bullshit for reals. so i’ll take the L on this one. i still say the shadow of the rings should be complete circles.

So, they used one of those “bump” things underneath her hair on the top of her head, which is what gives that extra dome shape and a cavity for her bottom layer of hair to get tucked in to. Then they did a ponytail with the top half of her hair, folded around the chain link, and tucked the excess tail inside. Use some of the hair starting from the bottom most side of the ponytail and wrap it around. That wrap around the base of the tail does not need to be separate from her hair. Easy to make it look like it is with some careful positioning. Plastic bands, hairspray, and potentially woven thread to really keep it all stable. The bump is what makes it all possible.

As for the cut off portion, I think it’s fake/not hers. You can kind of tell by the coloring not 100% matching her hair, but it is pretty much spot on.

Keep in mind they have a handy bundle of matching long hair strands. So they could use a clear elastic band to hold the short hair, then wrap it with matching long hair. Given that it’s for a significant event, the model might even have had slightly longer hair, and after forming that tiny bun the stylist cut off any excess.
