See I have almost perfect standard european measurements... have 48 cm shoulders so I should use size 48 that is equivalent to a US 38R, The 48 suits fit me almost perfect in shoulders, sleeve lenght, trousers waist and lenght, trousers come normally in size 32.
But I have a wider chest than the standard 38", I have 41" chest so I should use a 40R or 42R jacket , but those jackets have wider shoulders and longer sleeves...
So the best solution is simply to try them on, different makers cut them different, I discovered I have less problems with my chest with 2 button jackets and also that some makers do wider chest 3 button jackets than others... and it is best to take a jacket that fits well even if the upper button closes tight and then make it alter by a tailor, just make sure that there is enough fabric to perform the alteration see if the joints are wide enough.
Depending on the fit of the jacket, most suits marked "42R" will have ~35" waist or so, and can be taken in a few inches, as long as the suit itself fits in the shoulders, waist, etc, and if the chest is a bit tight, it's easy to go from 42" to 43" It's likely it'll have to be brought in a bit in the waist, but I imagine an off the rack 42-43 will be close, with the major adjustments that have to be made in the waist of the pants and jacket.
