There is no real "UK/US/EU/etc" sizing

As explained above, you will see that all sizing schemes come with exceptions. Reality is that there is no global entity that dictates and regulates how each manufacturer should size their bras according to their region.

Each manufacturer has the liberty to use whichever bands or cup lettering system they please or they think it is right, or even worse, change their minds at any point in time.

What you will find is that there are some rules that certain brands follow and other don't, so any regional sizing system will never be 100% precise across all brands that claim to use it.

Changing sizing schema

Some brands will change their sizing in time after they have produced certain bras.
