What I think is important to point out is that before Oortmas 2019, pretty much all the cosmetic items we had were static items affixed on the character’s head. When I mean static, I mean these 3D models weren’t required to twist with the character’s model.
The scarves we’ve had with Oortmas 2019 are different in that they’re affixed around the neck of the character and these models do twist to follow the character’s animations.
Maybe this never ever was an issue for the devs, but I still remember concept arts from a time where the clothing explorations were still planned to be sets of small static models affixed on various parts of the character’s body. So I do like to think it’s something they’ve figured out quite recently, and it might mean that actual clothing for our characters are coming sooner than we might think. 
Maybe @James can confirm or deny my above analysis? 
Maybe I’m just reading too much into it.
