When purchasing zippers for sex doll costumes, be sure to choose a style that can be "separated" like a jacket zipper. If the zipper you buy cannot be separated (for example, for clothing near the neckline), you will need to adjust it yourself or add padding.

The development of realistic materials has also played an important role in increasing the appeal of custom sex doll torsos. Modern manufacturing technologies have improved the texture, flexibility, and durability of materials used in these products. High-quality silicone and other advanced materials provide a more realistic appearance and tactile experience, helping manufacturers create products that better match consumer expectations. As material technology continues to improve, customers are increasingly viewing these products as carefully designed personal items rather than simple novelty products.
