Thanks gents for all the kind words. This is the first Havana-fit garment I've purchased from SuSu. Previously didn't fancy the high buttoning point. For a 3pc, this doesn't matter (and in any case I've heard that it's been lowered for this season - not sure whether my own suit has the higher or lower buttoning point).
Anyway I hover between a 50 and a 52 (EU) in most OTR brands. This suit is a 52 which appears to be ample. The jacket has had zero alteration of any kind, although at some point I might get the sleeves shortened by 1cm or so.
Oddly enough, the waistcoat was a 50 - someone had apparently done a sneaky little waistcoat swap-out at some previous point. SuitSupply graciously agreed to let out the waistcoat free of charge - they found another 2cm for me and it's perfect now. In fact I suspect it may fit me better than a 52 would have. I tried on a 54 waistcoat and was swimming in it.
