I got my 32S on Friday. I think it fits pretty well... it was just a tad bit snug feeling in the chest though, but I don't think it's too bad. I just know I can't really wear anything thicker than a thin sweater or cardigan underneath it without feeling really constricted. The length seems about perfect. I will post up some pics when I get back to my dorm where my tripod is, so I can actually produce some worthwhile pictures again (as opposed to mirror pics which I hate).
And @ ross: nope it wasn't a custom order... just a plain ol' 32S Classic in Black.
Edit: blindr... I'm around 5'4" and 125 lbs or so and got the 32S. It's pretty short but I believe it fits me correctly. If you want a little extra length, though, I would go with R. The coat is ridiculously warm, though... so I'm really pleased with that. The weather in Iowa has been extremely cold lately (last I checked it was -12° with a -34° wind chill) and the coat has held up very well and kept my body totally warm (my face is another story, however).
