Breast form companies have their own sizing charts. You always purchase breast forms by your bra band size and the cup size you would like to achieve.
Take a soft tape measure and measure around your body approximately 2 inches below your nipple. Looking in the mirror helps.
Pull the tape snug but not tight.
Make sure the tape is even all around your body and not hanging down in the back.
When you take this measurement, round to the closest whole inch, either up or down.
Example: If your measurement is 33 3/8", round to 33". If you measure 33 1/2" or more, round to 34".
Bra bands come in even numbers. If the rounded measurement you come up with is an even number, add 4 inches. If the rounded measurement you come up with is an odd number, add 5 inches.
Even measurement: 34" + 4" = 38 bra band
Uneven measurement: 33" + 5" = 38 bra band
PLEASE NOTE: This is an approximate band size to start working with. There are always exceptions. As the band size increases, so does the cup size of the bra. Therefore, a 38C is going to be smaller in the cup than a 40C. You would then try a 40B to maintain a similar cup size. This works the other way as well. If your 38C was too large in the band, then you would try a 36D to maintain your cup size.
The end result is 40B, 38C, and 36D would all wear the same breast form size.
Example done on a 38C pair of breast forms.
Your bra should fit you snug but not tight.
When purchasing your new bra, you should be doing it up on the center set of hooks.
If you can only comfortably do it up on the first set of hooks, making the bra fit the largest, then you need to go up in the band to a 40 and down in the cup to a B.
If you are doing your bra up on the third set of hooks, making the bra fit the smallest, then you need to go down in the band to a 36, but up in the cup to a D.
Your bra band should be even all around your body and not raised up in the back.
If it is, the fit is not good. Make sure you have adjusted your shoulder strap length first and if it is still raised in the back, you need to try a different bra style.
Your breast forms should be positioned and fit halfway between your elbow and your shoulder for a natural look.
Subdued/demure look is an AA/A cup
Average look is a B, Full B and C cup
Bold is a D or DD cup
Over a DD, you want to be noticed
Breast forms fit best in a full cut bra so the breast form is not visible. Demi cut, half cut, and padded bras do not work well with breast forms.
Before purchasing your breast forms, you need to decide on the style that will work best for you.
Take your soft measuring tape and measure around your body approximately 2 inches below your nipple.
Make sure the tape is pulled snug but not tight and is even all around your body. Example: 35 inches.
Next, take the tape measure and this time measure around the body but go through the middle of the nipple. Example: 37 inches.
Subtract the first measurement (35) from the second measurement (37). Example: 37 - 35 = 2 inch difference
If the difference is less than 1.5", you should be fine in a breast form that is fairly flat in the back to hug your chest wall.
If it is 1.5" to 3" difference, you need a form that is slightly hollowed out in the back to conform over your developed pec muscles/breast tissue. They are best suited for someone who is a flat to a natural AA/A cup.
If it is over 3", you need a full shell form that is hollowed out in back.
Go to our breast forms and click on the breast form that interests you.
Scroll down to the bottom of the page where the fitting chart is located.
Intersect your bra band size with the cup size you would like to attain.
This will give you the breast form size to order.
IMPORTANT NOTE: Every breast form fits differently. Always consult the fitting chart before ordering your breast forms to ensure that you are receiving the correct size.
How to use this fitting chart: Intersect your bra band size (the number) with the cup size you want to achieve. Where the two intersect, that is the breast form size that will fill that bra. Example: 40B is a size 6.

We do find that our AMOLUX Ruby breast forms work best when attached to go braless or when worn with our AMOLUX pocket bras.
Because our AMOLUX Ruby breast forms are only available in even sizes, each size of breast form may fit differently in your bra. To ensure the best fit for your body and for your bra, please do not hesitate to contact us.
Because our AMOLUX Diamond breast forms are only available in even sizes, each size of breast form may fit differently in your bra. To ensure the best fit for your body and for your bra, please do not hesitate to contact us.
The above fitting chart will give you a shallow to average cup fill. If you would like to achieve an average to full cup fill in the same size bra, you may go up one breast form size.
