I am researching a sex doll model

At first I was working on a large-scale doll model (160/165 cm) because I wanted to be more realistic and easier to wear, but then I realized that some models show more than 40 kg, so I think it’s located in a smaller model, so It is easy to carry and store (150 cm). Finally, I am worried that a small sex doll is very complicated to wear (I found something on this forum). And I am worried that this small part will make it look too young, and the cardboard at the bottom of these days is over. Can someone motivate me how to become the weight of a model?
