I have one from maybe late '07/early '08. It's a military-style olive green linen-y buttondown. I ended up getting the 34D-L, I think, after an exchange. I think I'd originally ordered either a 36D-R or a 34DD-R, and whichever it was, it was boxy and REALLY short (I'm 5'4" but with a fairly long torso, plus the bust, which takes up a good amount of north-south acreage). Anyway, I did an exchange for the 34D (to make it narrower) and swapped out the regular for the long, and I'm very happy with it. Most of my buttondowns don't have collar buttons, and I don't mind the double-buttons on the placket--I think it makes it look a little less "I may as well have gotten this from K-Mart", more dressmaker-y, a little more artisanal. I don't know. I'm nuts. I don't know whether they've changed the fits since then, though. (For the record, I take a 32F/DDD--around a 36.5-37" bust on a 27" waist--I usually wear a 4 or a 6.)
So, if you're at all tall, I might recommend getting the Long if you haven't already. Otherwise, please keep us updated on how it goes!
