Why didn't you just try them on since you were in the store? I tried on some of their slim chinos a year ago so not sure the sizing would be the same but I went down 2 sizes from a 33 to a 31 and it fit slim on me. I'd say the leg opening was 8". they have a different cut now. The davis? I think, and it is slimmer + lower rise than the other cuts, I believe its the one that's on special. They still have chinos in the less slim cut though. Yeah for their "kennedy" cut I usually size down two, which works surprisingly well... after sizing down its pretty slim and tapered w/out any weird proportions or pulling (at least for me). EDIT: for dr who - size down two on the 'kennedy' fit, the davis is TTS.
