How to Measure Your Doll for the Correct Bra Size
Finding clothing that fits a companion doll properly can be challenging, especially when shopping for bras, lingerie, bodysuits, dresses, and fitted tops. Human clothing sizes are not always consistent, and the proportions of a doll may not match standard clothing charts.
The good news is that determining a doll’s approximate bra size is fairly simple once you know two measurements:
- The fullest part of the bust
- The torso directly underneath the bust
At RealLoveSexDolls.com, we also include both the bust and underbust measurements already converted into inches on every doll listing.
The Two Measurements You Need
1. Bust Measurement
Measure around the fullest part of the doll’s bust.
The measuring tape should:
- Remain level around the body
- Fit snugly without compressing the breasts
- Pass across the fullest point of the bust
- Wrap around the bust only, under the arms
This measurement represents the doll’s full bust circumference.
2. Underbust Measurement
Measure around the doll’s torso directly underneath the breasts.
The measuring tape should sit snugly around the torso. Keep the tape straight and level around the body.
The underbust measurement provides the starting point for estimating the bra’s band size.
How to Calculate the Doll’s Cup Size
Subtract the underbust measurement from the full bust measurement:
Bust measurement − underbust measurement = cup-size difference
Use the difference in inches to estimate the cup size:
- 1 inch = A
- 2 inches = B
- 3 inches = C
- 4 inches = D
- 5 inches = DD or E
- 6 inches = DDD or F
- 7 inches = G
- 8 inches = H
- 9 inches = I
- 10 inches = J
- 11 inches = K
- 12 inches = L
- 13 inches = M
- 14 inches = N
- 15 inches = O
Example
Suppose a doll has the following measurements: Bust: 36 inches and Underbust: 32 inches
The calculation would be: 36 − 32 = 4 inches
A four-inch difference indicates a D cup. So doll’s bra size would be a 32D.
Important Bra-Fit Considerations
For the best results, look for bras with:
- Adjustable shoulder straps
- Stretchable band material
- Multiple hook-and-eye settings
- Soft or unlined cups
- Flexible underwire or no underwire
- Stretch lace or elastic fabric
- Light Colored fabric
Bra Bands Have Some Built-In Flexibility
Most traditional bras have three columns of hook-and-eye closures at the back. These adjustable settings allow the band to fit not only the exact labeled band size, but also torso measurements that fall slightly below or above it.
For example, a bra labeled with a 34-inch band may still work for a doll whose underbust measurement is close to that size, depending on the stretch of the fabric and which hook setting is used.
The loosest hook provides the most room, while the tightest hook creates a snugger fit. This added flexibility is helpful when a doll’s underbust measurement falls between standard bra sizes.
Stretchy bands, bralettes, and soft-cup bras generally offer more flexibility than rigid, heavily structured bras.

Tips for Dressing Your Doll Safely
Before dressing your doll:
- Remove jewelry, watches, and anything with sharp edges.
- Protect the fingers when pulling on sleeves.
- Avoid dark or strongly dyed clothing unless it has been tested for color transfer.
- Wash new clothing before placing it on the doll.
- Use light-colored undergarments.
- Support the doll’s weight and joints while changing outfits.
- Do not pull tightly on the arms, hands, breasts, or neck.
The correct fit should look flattering without placing unnecessary pressure on the doll’s body.
Finding Clothing for Your Doll
Knowing the doll’s measurements makes shopping much easier. Compare the doll measurements shown on the RLSD doll listing with the clothing manufacturer’s size chart.
