Picked up my first Kamakura at the NY shop a couple of days ago. I can't compare how the new "Manhattan" slim fits compared to the old ones, but this fits me great. Most of my OCBDs are from BB, mostly MiUSA and milano and the old BB "extra slim" fit. Got fitted. My neck size remains the same but I ended up getting a 34" arm. I'm usually a 32/32 or 33 in BB. Never a 34. Collar roll is great. Also, rather than get the thick oxford cloth, I went with this "panama" cloth, which is lightweight. They had a thinner fabric that was more see through (can't remember what it was called). Passed on it b/c I sometimes I wear my shirts w/o an undershirt and was afraid my nips would show. Great service and signed up for their frequent buyer club.
