I wear a 29 or a 30 in most jeans. I have 29 in TCB 50s and Slim 50s. Size 30 in TCB 60s (waist fits good with a roomy top block). Size 29 Boncoura 66.
I went with a size 30 for the 2009 , mostly on account of the slim legs. The legs are slimmer than your average straight fit. I only have a little bit of wear in them, so I can't say how the stretch will be, but I'm happy with the fit so far.
These are the measurements after I ran them through a hot wash (they are one- wash , but I'm obsessive about getting the shrinkage out. The only change was a small loss in length and negligible difference in leg opening.)
Leg opening 7.75"
@Max Power I did a hot wash before wear and Measure hardly any difference. Sugar Cane seems to shrink the hell out of their stuff. I think sizing up would be safe if you plan to wash frequently. If they are right now, they will be tight after every wash. How are the thighs on the 34? Reviews say these stretch out quite a lot.
