What bra size are you if im 45 inches across the breasts?

To determine your bra size, you will need to measure both your underbust and your overbust. The underbust measurement is taken around the body just below the breasts, and the overbust measurement is taken around the fullest part of the breasts. Once you have these two measurements, you can use a bra size calculator to determine your bra size.

For example, if your underbust measurement is 45 inches and your overbust measurement is 50 inches, your bra size would be a 45DD.

Here is a general guideline for determining your bra size based on your overbust measurement:

* Overbust measurement of 30 inches: bra size 30AA

* Overbust measurement of 32 inches: bra size 32AA

* Overbust measurement of 34 inches: bra size 34AA

* Overbust measurement of 36 inches: bra size 36AA

* Overbust measurement of 38 inches: bra size 38AA

* Overbust measurement of 40 inches: bra size 40AA

* Overbust measurement of 42 inches: bra size 42AA

* Overbust measurement of 44 inches: bra size 44AA

* Overbust measurement of 46 inches: bra size 46AA

* Overbust measurement of 48 inches: bra size 48AA

Please note that this is just a general guideline and that the best way to determine your bra size is to be fitted by a professional.
