How to Find a Sex Doll's Bra Size
To find a sex doll's bra size, wrap a soft tape around the underbust and the fullest part of the bust, then subtract. The underbust rounds to the band; the difference in inches sets the cup. A 160 cm doll typically lands near a 30 band, DD to G.
The hard part is tension. A doll has no ribcage to stop the tape and no muscle holding the bust in place, so four attempts give four sizes. The steps below fix the variables, then convert the result into a label size.
1. Silicone Material Introduction
Material decides how the tape behaves. Silicone is dimensionally stable: press a thumb into the bust and it springs back, so the tape reads close to true. TPE is softer, and a snug tape can read 1 to 2 cm small.
Both are hand-finished, so no two dolls match exactly. Spec sheets list bust, underbust, waist and hip in centimeters, with a tolerance of about ±1 to 2 cm. Treat those as reference; our guide to silicone vs tpe sex doll covers density and repairability.
How to Measure Bust and Underbust on a Doll
Stand the doll upright with the arms lifted about 15 degrees. Hanging arms distort the bust line.
Run a soft tape under the breast root, level front and back, and record to the nearest 0.5 cm.
Move the tape to the fullest part of the bust, parallel to the floor, and record it.
Repeat both readings. A gap over 2 cm means the tape is compressing material, not measuring it.
Gel-filled busts settle, so measure those after 24 hours upright.
Band and Cup Math
Divide the underbust in centimeters by 2.54 and round to the nearest even number: 71 cm is 27.9 inches, so the band is 28. Each inch of bust-minus-band is one cup letter.

Measure twice, once light and once snug. If the readings differ by more than 2 cm, the tape is compressing the material. Trust the lighter number.
2. Customization Options
Bra size is a fit question, and on a made-to-order doll it starts at the order form. Most makers offer a bust profile, and some accept a custom circumference for 5 to 15 percent above base price.
Bust Profiles and What They Change
A larger profile adds volume at the front and can widen the chest wall, so the bra changes even when the underbust does not. If you already own lingerie, compare its band and cup to the doll's spec first. Our notes on sex doll lingerie cover strap width on a rigid torso.
Gel-Filled, Hollow and Solid
Gel-filled breasts add 1 to 3 kg per pair and hang like soft tissue; hollow ones cut 1 to 2 kg but drape less. Gel settles overnight and can add a centimeter to a standing bust, shifting the cup one letter.
3. Buying Guide
Confirm the spec sheet before buying a garment. Bust and underbust are published in centimeters, sometimes with a nominal cup. Convert once and shop from that figure rather than the letter alone.
Read the Spec Sheet, Then Verify
Makers measure a finished mold, so numbers hold within a run but drift between runs; ±1 to 2 cm is normal. Buying ahead? Add 2 cm to the bust and pick a band that tightens by two hooks. Our walkthrough on how do i measure my sex dolls covers waist and hip too.
Bra Size Chart by Doll Height
Ranges come from common molds, not guarantees: a full bust sits at the top of a row, a slim build at the bottom. Cup letters here follow the maker's label, which runs smaller than raw math.

Why Standard Sizing Fails
Three things break a human bra on a doll. Ribcages are often narrower than the smallest human bands, so a 32 hangs loose. Shoulders sit further back, so straps slide. And the surface has no grip, so straps and bands migrate.
Favor adjustable straps, three or more hook rows, and four-way stretch. A soft bralette spanning two band sizes fits better than a rigid underwire in the right size. If the bra must be structured, size up one band. Our notes on sex doll clothing sizes map retail labels to doll frames.

A Buying Checklist
Measure twice; accept the lighter reading within 2 cm.
Round the band to the nearest even inch, and sister-size up on rigid fabric.
Keep band height at 8 to 12 mm so the elastic does not dig in.
Spend $8 to $40 on a first bra, not $120, until the size is proven.
Skip metal underwires on TPE; pressure marks can become permanent.
4. Maintenance & Care
A bra that fits on day one can leave marks by day thirty, because the material changes, not the garment. TPE relaxes and can settle 1 to 3 cm at the bust in the first months.
Before the First Wear
Wash every new garment twice in cold water before it touches the doll; unfixed dye is the leading cause of TPE staining. Dry it fully, since damp fabric holds dye against the surface.
While Dressed and in Storage
Remove a bra within 24 hours. Check under the band for marks deeper than a millimeter; if you find them, the band is too tight. Powder the underbust before dressing a TPE doll.
Store bras flat, never stretched over the bust for weeks. Constant tension flattens elastic and prints a line into soft TPE. Keep the doll in loose cotton, below about 25°C.
5. Shipping & Privacy Policy
Most orders are for dolls, but both follow the same rules. Dolls are built to order and typically ship within 7 to 20 business days, then transit time depends on destination. Outer cartons are plain and unbranded, and billing descriptors are neutral.
Age Verification and Payment
Every order requires an 18+ confirmation. Card processors treat adult retail as a restricted category, so some banks decline the first attempt or ask for phone authorization. These limits come from providers, not the retailer.
Customs and Import Rules
We do not promise any customs outcome. Duties, taxes and inspection belong to the authorities in your country and are the buyer's responsibility. Check local rules first. This is general information, not legal or financial advice.

Fit Help Before You Order
If a spec sheet lists bust and underbust but no cup, send both numbers and we will convert them before your doll is built. Sizing guidance is free and commits you to nothing.
Warranty, Returns and Hygiene
Manufacturing defects are covered for the window stated on each product page, commonly 6 to 12 months: seam separation, skeleton faults under normal use, motor faults on feature models. Dye transfer, pressure marks and cosmetic wear are not.
Intimate garments and opened figures count as hygiene items in most jurisdictions, so returns are limited once packaging is opened. Inspect a bra before removing tags.
Frequently Asked Questions
How do I measure a sex doll's bra size at home?
Stand the doll upright and wrap a soft tape around the underbust, keeping it level. Round that number to the nearest even inch for the band. Measure the fullest part of the bust the same way, then subtract the band from the bust. The difference in inches gives the cup letter.
What is the difference between band and cup on a doll?
The band is the circumference of the ribcage under the bust, so it describes torso width. The cup is the volume difference between bust and band. Two dolls can wear the same cup letter and need different bras, because a 6 inch gap on a 26 band is much smaller than on a 34.
Why doesn't a standard 32C bra fit my doll?
Human bras assume a ribcage that flexes, shoulders that hold straps, and skin that grips fabric. A doll torso is rigid and often narrower than a human 32 band. The cup may be right while the band gapes or the straps slide. Choose bras with adjustable straps and several hook rows.
Can I use a human bra size chart for a sex doll?
As a starting point, yes, because the math is identical. In practice, treat the result as a range. Doll measurements are hand-finished within about 1 to 2 cm, and small brands letter cups differently. Convert the centimeter spec to inches, calculate the size, then confirm against the garment's own size table.
How tight should the tape be when measuring?
Snug enough to sit flat against the surface, no tighter. On TPE, a firmly pulled tape can compress the material and read 1 to 2 cm small, which pushes you into a band that is too tight. Take two readings and use the larger one if they differ by more than 2 cm.
Do silicone and TPE dolls measure the same?
The tape method is the same, but the reading is not always identical. Silicone resists compression, so it measures true. TPE yields under the tape, so the same mold can read 1 to 2 cm smaller in TPE. When comparing two dolls, measure both rather than assuming the spec transfers.
What bra size does a 160 cm sex doll usually wear?
Most 160 cm dolls have an underbust between 68 and 76 cm and a bust between 84 and 96 cm, which works out to roughly a 28 to 30 band with a DD to G cup. That is a range, not a rule. Check the individual spec sheet, because brands differ by several centimeters.
What if the measurements fall between two band sizes?
Round down to the smaller even band and add one cup letter, which is the standard sister-size adjustment. On a doll, round up instead if the bra has no stretch, because a rigid band that cannot close is useless. Buy both sizes when they are cheap and keep the one that fits.
Will a bra stain a TPE doll?
It can. TPE is porous and absorbs dye from dark or saturated fabrics, sometimes within hours in warm conditions. Wash new garments twice before dressing the doll, prefer light colors for long wear, and remove the bra within a day. Silicone resists dye transfer better but is not immune.
How often should I re-measure a doll for bras?
Measure once when the doll arrives and again after a month of use, since TPE relaxes slightly and can settle by 1 to 3 cm at the bust. After that, check every six months or whenever a bra that used to fit starts to gap or leaves deep marks.
Final Thoughts
A doll's bra size is two numbers and one subtraction. Everything after that is judgment: how much the material compresses, how much tolerance the maker allows, how much stretch the garment offers. Treat the result as a starting point.
Buy one inexpensive bra first. Wear it a week, check for marks under the band, and adjust from what you see. That loop beats any chart, including these.
