The Sizing will depend on the PDC style jeans and if they are stretch / stretch not. I only tried Blue PDC mergers. I wear a 28 (10) in the S and B EVH and 28 Mergers in Blue. This particular style represents a little looser than S and B. It is best to go with the size of your jeans and ask any...
I worked on my second pair of Nudies, SJ, love the Nudies, never back denim cheap, definitely worth it. Next take a couple of RAW photos probably will not, however, the thought of moving Nudies Naked & Famous or perhaps APC.
