Sizing Breast Forms for a Perfect Fit


Breast forms make a lot of difference for cross-dressers and help us to create a believable cleavage.


But if your goal is maintaining realism, you must keep an eye on proportions and find the correct size of forms.


The problem is that some of us may not know how to, as it requires you to follow a few steps.


Sizing Breast Forms for a Perfect Fit


You must gather a little information, such as your preferences in breast shape and a few measurements.


After that, you’ll still have to compare this kind of information to a few charts to make sure everything looks proportional.


And in the end, you may proceed to find an appropriate bra.




To help you size your forms correctly, this article includes a step-by-step guide on this matter.


If you follow this guide and follow these instructions as given, you may be able to achieve a perfect fit.



Step 1: Get yourself some privacy

This measuring process requires a certain degree of privacy.


You’ll have to take out your clothes and pay attention to charts and measurements, so it’s wise to avoid interference from outside.


Besides that, measuring your chest in front of other people may raise suspicions about your cross-dressing habits.


I recommend you do that in your room or the bathroom at night.


That’s so you can pay full attention to this process, preventing you from making mistakes.


It also prevents you from getting distracted or having other people find out about it.


Step 2: Determine how full the cup should be

Women’s breasts have several possible shapes, and breast forms try to replicate them.


With that in mind, you might as well choose the shape you like the most.


The most common, or average per se, is the medium-looking cup, shaped like water drops in a symmetrical position.


After that, there’s the “shallow cup,” shaped somewhat like an “L,” with more volume on the bottom.


And last but not least, you may also choose a “full cup,” which is round in all directions.


Alignment also varies, but most forms available are aligned symmetrically to the center.

Nonetheless, you may still find some other models point outwards, or some less-symmetrical ones.


The choice is up to you and your preferences, but still, I would recommend you to do so based on your frame.


If you have narrow shoulders, for example, a shallow cup will be more convincing.


Asymmetrical average cups, on the other hand, will look better in a wider frame.


Step 3: Measuring your band and bust sizes

The first measurement here is your band size.


To find it, you shall use a tape measurement of either inches or centimeters.


Most brands will give you measuring charts based on inches, but measuring again in centimeters may be useful, depending on where you live.


Place the tape under your arms, about two inches below your nipples.


Please measure the circumference of your chest in this region and write it down. That is your band size.

To get your bust size, repeat this process, now with the tape right around the middle of your chest where your nipples are.


But this time, extend the tape up to how far you would like your breasts to go.


For a more realistic look, avoid exaggerations and consider both your height and weight.


Now, most companies use even numbers as a reference on their charts.


So, if you get an odd number on either of these measurements, I recommend rounding it down a number so you get an even one to compare.


Step 4: Getting your cup size

Now that you have both the previous measurements, you can find your cup size.


Some people say that you can simplify this task by following a general rule.


That would be choosing a B or C cup if your frame is small, C or D if you have a medium frame, and D or higher for larger frames.


But by doing that, your measurements won’t be as precise, and the forms won’t fit so perfectly.


Instead, what you have to do is subtract your band size from your bust measurement and then compare it to a conversion chart.


Here’s one as an example:


Step 5: Compare your band and cup sizes to the charts

What you have to do now is compare the measurements and your objectives with charts provided by the manufacturers.


It varies from one brand to another, but in general, they will be based on that.


It’s important to do this kind of comparison because each brand also has its way of cataloging form sizes.


But if you provide these measurements to them, you’ll be able to find one that fits your frame more convincingly.




To find a perfect fit when looking for breast forms, avoid shortcuts and exaggerations.


To achieve a realistic result, you must take precise measurements, ensuring the forms are better suited for your frame.


I also recommend you do so with certain privacy so you can focus on the measurements to get them right.


After all of that, it’s all a matter of doing basic maths and comparing size charts.

  1. I’m still a little unsure as I know cup size varies with band size (normally)
    If I normally wear an 18D (40D) bra comfortably, what size breast plate would suit?
