Customization options for realistic sex dolls span appearance, anatomy, and function. A foundational choice is skin tone—ranging from pale to deep hues with subtle undertones—plus texture depth to imitate natural skin. Facial customization often includes eye color, eyelash length, lip fullness, and cheek contour. Hair options vary from color, length, wave pattern, to scalp density and hairline realism. Body customization covers height, weight distribution, breast shape, muscle definition, and finger/toe detailing. Joint articulation can enhance poseability, with options for more flexible wrists, elbows, knees, and neck movement. Additional features may include customizable orifices, or tongue and mouth options, and even heat or tactile responses in certain models. Quality considerations include silicone or TPE composition, seam placement, and the durability of paint or airbrushed details. Aftercare features, like removable, washable internal linings or easy-clean surfaces, can simplify maintenance. Finally, ensure alignments between your budget and desired realism, and confirm safety standards, warranties, and return policies before committing to a design.
