I have Assos 3/4 in M, I am 5"6' 64kg 30W and they fit fine.
I'm 6'2" 72KG 33W and the Assos medium fit perfectly (well, a little snug but better than having movement in the large).
I know, as I just tried on the large and the medium before purchasing the medium.
Also looked at the Castelli bib shorts whilst I was there, but even though they talk the talk (in terms of marketing waffle on all of the labels) the pads are nowhere near as nice as the Assos ones.
