Is 36C big?

Shopping notes for 36C

Confirm the size first: two minutes with the calculator beats inheriting a label. Then let the brand decoder translate 36C into each brand's cut, since the same tag runs shallow at mall brands and deep at UK houses. If 36C passes the band checks but the cup misbehaves, that is usually shape, not size.
