Thanks to everyone who has contributed sizing feedback on this thread. I bought a pair of PNS in raw black from Mr Porter, in size 33. I'm a true size 34 and tend to size down to 32 for N&F jeans. I like the fit of the PNS for my thighs but I can button up with relative ease. Based on the feedback on this thread I'm guessing size 33 is still a bit too large for me so I think I'll be returning them. Shame, got them for a good price.
