That sucks. I almost bought a pair of those Lot 54BB in 36 as well. I decided the rise was too high for me and actually ended up sizing down 1 on a pair of 64s LHT instead. One thing to note is that MF measures the thigh straight across from the crotch (not an inch down like SE and many others). There's also the "how do you measure/estimate the top block?" problem. So, you end up with thigh and waist measurements that compare favorably to other jeans you own and then you still discover, as @shredwin_206 notes, that MF tend to be to run "quite snug in the arse."
