If it gets dirty, I know that any color transfer will be limited to the soles of the feet. Nice to hear you find the real sex doll problem. They are helpful, but they can only help in some way, so the doll’s head is usually smaller than ours. The solution around this problem is to modify the wig waffle (the tutorial is also on the tube), or to spend a little money on high quality wigs, you can choose to order different hair sizes.
This is something we all live together and find our own real sex doll method. I just used a lock washer between the head and body, which seemed to work well for me, but different brands may vary. For garter / leggings, make the outer layer of the leggings one more layer so that the straps on the garter don’t need to touch the doll’s legs directly. Is this common sense … I only found out when cleaning up dolls for sale.
If there is any slight discoloration, it can be rubbed with a hard / fast paper towel (which creates a certain amount of friction), and the outer layer of the TPE will “melt”, pile up, and then pick it up. I had the same problem with my real sex dolls head. When fully tightened, she will face unnatural difficulties. I tried the plumber tape but it didn’t help. I like the idea of using a rubber washer and I will try it out.
