Yep, that's a 34R. Bear in mind that I'm typically a (very) Short in almost every brand, and you get an idea how short the Havana cut is. The jacket length was shortened a further 0.5" or so from standard though (for a first purchase from SS, I decided to let the salesperson decide most aspects of the alterations, just to see how well they'd handle the whole process). It's the shortest jacket in my wardrobe except a BBBF BB0 that's 0.25" shorter (no length alteration on that one), but the BBBF has more closed fronts so it doesn't appear as short as the more open Havana. I think that in future, I won't get a Havana shortened (or at least, not by quite as much). That's a minor thing though; I'm content with the length on this one as it currently is, as a different option to have within my wardrobe.
And thanks for the +ve feedback, mrjester!
