Sex Doll Customization

You finally decided that you’re going to get a realistic sex doll. You browsed through a wide selection of dolls and found the perfect one for you: your dream silicone sex doll. However, you’re suddenly overwhelmed by all the sex doll customization options and possibilities.

Standing Feet, Removable Vagina, Hollow Breasts? What do all these options mean and which ones are right for you?

Read our detailed and straight-to-the-point guide to find out!

Your sex doll’s height is an important choice to make. It will determine how tall she is, how much she weighs, and her body type. A general rule of thumb is: The taller the doll, the heavier it is. Taller dolls also tend to be more expensive. Because heads and bodies can be mixed and matched, it’s a good idea to focus on the height, weight, and body first. Usually manufacturers will have already chosen the best head and body combinations for their photos.


Sex dolls are usually heavier than most people realize. For example, a 150 cm doll is usually around 30-32 kg (66-70 pounds) and a 170 cm doll is usually around 40+ kg (88+ pounds, up to 120+ pounds). It may not sound so bad, but sex dolls are all dead weight and much harder to lift than an actual person. Sex dolls also have an awkward weight distribution so it can be a struggle. If you have back issues, it’s best to opt for a smaller doll due to the weight. Dolls above 130 cm or 140 cmshould still feel perfectly natural for sex and companionship no matter your height.

Eye and Skin Color

This is fairly self-explanatory and does not require much explanation. Most sex dolls have eye color and skin color customization. Simply choose the color you like best. Note that sometimes the skin color in photos are misleading due to the professional lighting used. Try finding factory photos or customer photos of the doll to get a better idea of the color.

Eyes can easily be taken out and replaced, so you can experiment with different colors, but the Skin color is permanent and cannot be changed.

Feet Type

There are 2 different Feet Types:Normal Feet and Standing Feet. As the name suggests, Normal Feet cannot stand while Standing Feet can stand. How can the Standing Feet stand you may ask? Because it has metal bolts attached to the foot plate that can hold the weight of the doll.

We highly recommend the Standing Feet option.

Here is a simple diagram of the metal plate inside the sex doll’s feet. Sex Dolls with Normal Feet should never stand, otherwise the weight of the doll will crush the TPE material below the metal plate and damage the feet. The Standing Feet, on the other hand, has bolts (visible from the bottom) that can hold the weight of the doll without damaging the feet. The bolts take on the weight so the TPE material under the feet is unaffected.

The reason we recommend the Standing Feet option is because it gives so much more possibilities. You can stand your doll for posing, photoshoots, sex positions, and storage. With the Normal Feet option, your doll can only sit and lay down. A lot of possibilities are lost and the feet will get damaged if the doll is placed in a standing position for any reason. In the long term, the Standing Feet option will enhance your experience by a lot.

Note: Some silicone manufacturers now offer Standing Without Bolts, an option in which the feet material is hardened to support the weight of the doll. It looks like Normal Feet, but feels much harder. It works farily well, but if left standing too long, it can still damage the bottom of the feet.

Sex Doll – Vagina Type

There are 2 vagina types: Removable and Built-in (Fixed).Removable Vaginas can be inserted and removed from the sex doll’s vaginal cavity. Therefore, it is easy to take out and clean after use, and can be replaced if broken.Built-in Vaginas are built into the doll, meaning they are permanently attached and cannot be removed. They are usually more realistic in appearance due to the fact that they’re built in, but it comes at a cost. It is much more work to clean a Built-in Vagina since it is attached to the doll. Cleaning usually consists of douching and rinsing the vagina with water over a pot or bucket, or in a tub, and then thoroughly drying it. Many Built-in Vagina doll owners use male or female condoms for intercourse with their doll to save the trouble of cleaning it.

Removable Vagina (Insert) Pros Cons:

+ Easy to clean, Replaceable
May not look or feel as realistic, Some sex doll owners reported that they can feel the insert moving inside during use Tends to be noticeably tighter than Built-in.

Because the removable insert goes in past the entrance of the vagina, there is about an inch of empty space at the entrance you have to pass through (it’s a con depending on your size)

Built-in Vagina (Fixed) Pros Cons:

+ Looks and feels more realistic
Harder to clean, Material can tear and is not replaceable

We recommend Built-in Vagina. They tend to be more detailed, look and feel more realistic, and is not as tight as the Removable. It may be harder to clean, but most doll owners prefer this option.

Breast Type

There are 3 breasts type:Solid, Hollow and Gel-Filled (not all brands offer Gel-filled).Solid breasts are filled with the same TPE material as the skin of the sex doll. They are called solid because the entire breast is filled with the TPE material.Hollow breasts have a pocket of air inside the breasts, hence the name Hollow.By having a hollow interior in the breasts, it allows you to squeeze the the breasts more easily, which makes them feel softer and squishier, resulting in more bounce and jiggle.Gel-Filled breasts are filled with very soft gel that feels extremely realistic. They are jiggly like Hollow breasts, have a natural weight to them, and feel much nicer, but usually costs extra.

At the moment, our personal ranking from best to worst is Gel-Filled, Hollow, Solid. However, the size of the breasts plays a part too.

Different Breast Advice

Solid Breasts are usually used for smaller breasts (B/C-cup and below) because there isn’t enough space to create the air pocket or to fill with Gel in the breasts. This is not a bad thing because small breasts are the most realistic as Solid. Hollow Breasts are usually used for larger breasts (C/D-cup and above). Gel-Filled is a new option and is also available for large breasts (but not for extremely large breasts otherwise it can burst during shipping or weigh down the breasts too much).

So the general rule of thumb is, Small Breasts = Solid, Large Breasts = Hollow or Gel-Filled. Some doll owners prefer solid large breasts too, which is a personal preference and also increases the weight slightly. Between Gel-Filled and Hollow breasts, Gel-Filled is usually better. It generally feels much nicer and more realistic than Hollow. It also adds a bit of natural weight compared to Hollow. Hollow is still good if you dont want to spend the extra money on Gel-Filled.

Note: Because Gel breasts add some weight to the breasts, it’s best to keep the breasts supported (i.e. with a bra) so the weight doesn’t pull/tear the breasts from the doll.


Most doll brands have a collection of wigs for you to choose from. These are wigs they have stored in their warehouses, ready to be included in all their doll orders. For some brands, you will notice that they don’t offer the wig seen in the photos. Many companies hire professional photographers who use their own makeup and wigs, and thus aren’t offered by the factory. Some brands like Doll Forever and Piper Doll do come with all the wigs seen in the photos. You should ask your vendor just in case. The wigs goes on your doll easily like a cap, and can be easily changed and replaced. Because most manufacturer’s wigs are fairly poor quality, you will probably end up buying another wig elsewhere.

Pubic Hair

Many doll brands offer pubic hair options. This is not a very popular option. Most people choose No Pubic Hair.If you choose to add public hair, it usually involves a fee, and then the public hair is implanted into the area of the skin. Unlike a wig, the public hair cannot be removed. Make sure to ask the vendor or factory for an example photo of the pubic hair because most of the time, it doesn’t look good. It can also fall out like all implanted hair.

Fingernail/Toenail Color

Almost all doll brands have the same fingernail and toenail color options. The colors usually include Natural Pink or Nude/Flesh colors (shown above), and Nail Polish colors(shown below). Note that the fingernail and toenail color is not painted on. The fingernail material itself is colored, meaning if you choose Pink,it will always be pink (it does not wash off). Choose the one you like best.

Other cosmetic options for your sex doll

Most doll brands also have additional cosmetic options such as areola color and size, vagina labia color, and more. These are pretty self-explanatory. All of these cosmetic options are temporary. Like the doll’s makeup, they are painted on and will eventually come off and will have to be re-applied.

There are also many Brand Specific Options. Some brands offer options that other brands don’t, like Sino Doll’s special RRS makeup which is expensive and not worth it in my opinion because it is only temporary. Also you should never get an electronic add-on like heating system, moaning system, etc. The electronic add-ons are really bad. Doll manufacturers are good at making dolls but terrible at electronics, so don’t pay more for the electronic options. If you want to heat up your doll, use an electric blanket.

Surely, Silicone Sex Doll is better than TPE Material in terms of heat resistance. You can follow the article :TPE vs Silicone Sex Dolls.What are the best Sex Dolls?

More Choice for Your Sex Doll

Many silicone sex doll manufacturers now offer the implanted hair option. It is expensive but looks more natural than a wig. Personally, I would not recommend it because it will eventually shed and fall out due to how it’s implanted, and it is harder to clean because it is attached to the doll’s head. It stays on longer on silicone heads compared to TPE heads due to the material, but keep in mind that the hairs can still eventually shed. It looks great for photography, and it’s better than stick with a wig in my opinion.
