Question 1

Why do bra sizes change between countries?

Accepted Answer

Band labels are based on either inches or centimeters, and cup letters escalate differently by market. That’s why a 34D in the US maps to 75D in the EU and 90D in France.

Question 2

How do I convert if I’m between band sizes?

Accepted Answer

Start with the closest band shown in the chart, then test the sister size above or below. For example, if 34 feels tight, convert the 36 band and drop the cup one letter to keep the same volume.

Question 3

What measurements should I keep on hand?

Accepted Answer

Keep your snug underbust plus at least one bust measurement. For fuller busts, add leaning and lying measurements to check which cup depth feels best across brands.
