Bra size calculator
This isn’t the calculator you’re looking for! This is:https://www.abrathatfits.org/calculator.phpThe biggest problem is that bra sizes are a measurement of volume, not just circumference. Stores will typically use a formula that lumps you into similar “sister sizes” so they don’t have to carry as many sizes. For example, a 32DD is very similar to a 40A, so most stores don’t carry 40 and push everyone towards 32.Which is the same as going to a restaurant which gives you soup in a tall glass because it holds nearly as much soup as a bowl.
