Standing 158 cm tall, she strikes a wonderful balance between lifelike presence and practical ownership. Her 88/62/96 cm figure combines a softly defined waist with natural curves, creating a silhouette that feels sophisticated, graceful, and incredibly easy to admire. As part of Irontech's acclaimed Natural Optimized Series, Nia goes beyond simple measurements. Her body has been sculpted with enhanced anatomical detail, realistic body transitions, and subtle contours that create a more authentic visual experience. Combined with premium silicone construction, the EVO skeleton system, ROS MAX upgrades, and a comprehensive list of included features, Nia offers a level of craftsmanship that stands out within the premium silicone category. ### Beauty Inspired by Natural Femininity Nia's design philosophy is simple: beauty through balance. Instead of oversized curves or dramatic proportions, she focuses on realistic feminine harmony. Every line of her body flows naturally into the next, creating a figure that feels elegant from every viewing angle. Key specifications: * Height: 158 cm * Material: Premium silicone * Series: Natural Optimized Series * Full-size feminine body * Enhanced realism package Her proportions create a doll that feels mature, sophisticated, and timeless. She is the type of model whose appeal grows stronger the more closely you look. ### A Soft Hourglass Silhouette Nia's measurements create a naturally attractive figure that emphasizes proportion rather than excess. Body measurements: * Bust: 88 cm * Underbust: 65 cm * Waist: 62 cm * Hips: 96 cm The 62 cm waist gives her body elegant definition, creating a beautiful transition between the bust and hips. Her 96 cm hips add softness and femininity, while the 88 cm bust maintains excellent balance throughout the figure. Together, these proportions create a silhouette that feels graceful rather than exaggerated. Her shape is attractive because it looks natural, allowing the entire body to work together as a complete design. ### Natural Optimized Series Body Design One of the biggest differences between Nia and more conventional silicone dolls is the level of sculpting built into her body. The Natural Optimized Series focuses on subtle anatomical realism that creates greater visual depth and sophistication. Enhanced sculpting includes: * Defined collarbone structure * Natural torso contouring * Refined waist transitions * Enhanced body realism * Improved anatomical definition These details may appear subtle at first glance, but they contribute significantly to the overall presentation. They help create a doll that feels more lifelike and visually engaging without sacrificing softness or femininity. ### Premium Silicone Craftsmanship Nia is crafted entirely from silicone, giving her body a refined finish that enhances every contour and detail. Benefits include: * Smooth silicone texture * Premium body definition * Crisp sculpt details * Refined overall appearance The silicone material allows smaller body features to remain visible and well-defined. Curves appear cleaner, transitions look more natural, and the overall figure feels more polished. This premium finish is one of the reasons silicone remains highly desirable among buyers looking for realism and visual quality. ### Full-Body Proportions That Feel Complete Nia's supporting measurements help maintain balance throughout the entire figure. Additional dimensions: * Shoulder width: 37 cm * Arm length: 67 cm * Leg length: 73 cm * Foot length: 22 cm These measurements create a body that feels cohesive from head to toe. Her shoulders remain feminine and proportional, while her leg length contributes to a graceful overall profile. Nothing feels oversized or out of place. Every dimension supports the same realistic design philosophy. ### EVO Skeleton for Flexible Posing Inside the silicone body is Irontech's EVO skeleton system, designed to provide enhanced movement and positioning flexibility. Features include: * EVO skeleton * Flexible body movement * Improved pose stability * Enhanced display options The skeleton allows Nia to be styled and displayed in a wide variety of natural-looking positions. Whether seated, standing, or arranged for photography, she can maintain realistic posture and presentation. This flexibility significantly expands styling possibilities and helps keep the ownership experience engaging over time. ### Articulation That Enhances Realism Nia includes several premium structural upgrades that improve both display quality and body realism. Included features: * Articulated fingers * Hard hands * Standing feet without visible bolts * Enhanced joint articulation Articulated fingers allow for more expressive hand positioning, while standing feet create cleaner display options. These details may seem small individually, but together they contribute to a noticeably more realistic presentation. ### Beauty Details That Bring Her to Life A premium doll is often defined by the quality of its finishing work, and Nia includes a strong collection of cosmetic enhancements. Included beauty package: * Implanted eyebrows * Implanted eyelashes * Handmade custom eyes * S+ makeup * S+ body painting These details help create a more expressive face and a more polished overall appearance. The handmade eyes add character and depth, while the makeup and body painting provide subtle realism throughout the figure. Together, these upgrades help transform Nia into a doll that feels uniquely refined and visually captivating. ### Included Premium Upgrades Nia arrives with an impressive collection of factory upgrades already included. Package highlights: * ROS MAX upgrade * Gel breast * Gel butt * Heating rod * Irrigator These additions increase both value and realism while helping create a more complete ownership experience right from the beginning. The package feels thoughtfully configured rather than stripped down to a basic setup. ### Designed for Styling Nia's realistic proportions make her incredibly versatile when it comes to clothing and presentation. She pairs beautifully with: * Casual fashion * Elegant dresses * Sleepwear * Fashion styling * Luxury-inspired outfits Because her figure remains balanced and realistic, clothing naturally complements her shape rather than overwhelming it. This versatility allows owners to create many different looks while preserving the graceful character that defines the doll. ### Why Nia Stands Out Nia offers a combination of realism, premium craftsmanship, and balanced beauty that many buyers actively seek. Highlights include: * Natural Optimized Series body * Premium silicone construction * 158 cm realistic height * EVO skeleton system * ROS MAX upgrade package * 88/62/96 cm proportions * Extensive beauty enhancements She appeals particularly well to buyers who appreciate realism, elegance, and a more sophisticated interpretation of feminine beauty. ### A Premium Silicone Doll With Timeless Appeal Irontech Nia captures everything that makes the Natural Optimized Series so desirable. Her 158 cm frame provides realistic full-size presence, while her 88/62/96 cm proportions create a beautifully balanced silhouette that feels feminine, graceful, and naturally attractive. The enhanced anatomical sculpting adds depth and realism throughout the body, while the premium silicone construction showcases every contour with exceptional clarity. Combined with the EVO skeleton, ROS MAX upgrades, premium beauty package, and extensive included features, Nia delivers an ownership experience centered on quality, realism, and refined elegance. She is a doll designed not to overwhelm with excess, but to impress through craftsmanship, balance, and lasting beauty. ## Categories [Most Popular Silicone Sex Dolls](/dolls/most-popular-silicone-sex-dolls/), [Best Selling Silicone Dolls](/dolls/best-selling-silicone-dolls/), [E-Cup](/dolls/e-cup/), [Female](/dolls/female/), [Asian Sex Doll](/dolls/asian-sex-doll/), [Medium Breast Sex Doll](/dolls/medium-breast-sex-doll/), [Top Rated Sex Dolls](/dolls/top-rated-sex-dolls/), [BBW Sex Doll](/dolls/bbw-sex-doll/), [Big Booty Sex Doll](/dolls/big-booty-sex-doll/), [31-35kg (68-77 lbs)](/dolls/31-35kg-68-77-lbs/), [150-159cm/4ft11-5ft2](/dolls/150-159cm-4ft11-5ft2/). ## Related and recommended dolls | Doll | Brand | Height | Cup | Material | Price | |---|---|---|---|---|---| | [Fanreal Gina BOSS](/fanreal-doll/gina-boss/) | Fanreal | 170 cm | D | Medical Platinum Silicone | $2,880 | | [Fanreal Maria BILLIARDS](/fanreal-doll/maria-ros-billiards/) | Fanreal | 170 cm | D | Medical Platinum Silicone | $2,880 | | [Fanreal Xue LS](/fanreal-doll/xue-ls/) | Fanreal | 162 cm | C | Medical Platinum Silicone | $2,880 | | [Fanreal Qian BEAUTY](/fanreal-doll/qian-beauty/) | Fanreal | 158 cm | B | Medical Platinum Silicone | $2,780 | ## Shipping, warranty and returns - **Authorized Seller.** Your safety is certified.
