I found the "classic tailoring/modern fit" sizing to be a bit too snug around the quads and seat for a 36 in, comparably the overall fitting of the 36 in. waist in the ridge line relaxed pants are spot on for me. Otherwise the build and materials are top quality that 13th Heaven is know for. I may step up a size to see if I can achieve the fit I am looking for.
Great pants. Wore them for the first time today and I’m already ordering a second pair. They sit comfortably on the hip, don’t ride up when squatting or sitting, and the legs don’t twist when I’m walking. The crotch area stretches where it should. The zippered leg pockets are a plus, great for my phone and wallet. 10/10 would recommend
