[Val_]

Thanks Valerie, I've gone for a 38a push up bra. I'll post a pic once it arrives. I measure 37 under bust at the mo and 41 across the bust but I'm now on a diet to drop around 15/20 lbs so I could already be on the lookout for my next investment

I would say based on this, a 36B sounds about right. Try taking a "break the tape" underbust measurement. What this means is to pull the tape as tight as you can.

I wrote a bra guide here: http://breastnexus.com/showthread.php?tid=23848

From my experience, Asian bra sizes are generally smaller than US sizes, so an Asian 80B might not fit like a non-Asian 36B.
