What is my bra size UK?
Many women and girls are in between two possible sizes.
This is normal.
But how to find your best bra size?
It is really a thing of trial in error.
You might have to try 2 or 3 different sizes.
It might be you fit different sizes just fine. Also depending on the bra style and the fitting of the different brands.
Remember: going up or down a band size will automatically change the volume of the cup size.
- 40A and 38B both have the same cup volume
- 34D and 36D do not have the same cup volume
How do I calculate my bra size?
Using a calculator or a bra size chart is a great way to help you find your size.
My advice is to play around with the calculator. Then you’ll see how close sizes can be!
