I love this link! Measurement: 28 underbust, 36 overbust and 32.5 above bust. American companies tell me I'm a 34B or 34C, 34D, 32c etc. this gives most accurate fit 32D (USA, UK, Australia). Bought the most comfy and flattering bra (that does not squash, pinch, ride up, slide down, gape at cups, no back bilbil too) from Marks and Spencer.
