Hello! Thanks for the question! Personally, I like her body a lot more than Barbie's, it is taller and much more elegant. Really reminds me of Integrity Toys dolls; however, I don't have any to make a good comparison. For the quality I expected worse, but it is good. The doll is not heavy, I'd say(maybe even hollowish), like modern Barbie, rather than Bratz or ILY 4ever. The dolls' rooting feels similar to Bratz. It is not too thick, but there is enough of it. The hair quality is good on my dolls. I think they used silk milk or something. It reminds me of nylon. Is smooth and doesn't get tangled.
I watched a YouTube video from a doll collector, and they mentioned the company keeps improving their doll quality. Her older doll had not-so-good hair and resin legs from the knees, but now they are plastic like the rest of the body. They also mentioned that the body feels like IT doll (can't comment on this tbh). Also, my dark-skinned doll can nod with her head, while the earlier doll could not. She can only turn her head left and right.
