Re: DH's, I did a ton of reading on that and it's a whole big mess of recomendations, but I think it's pretty simple. Know these three things: 1. Your true waist size 2. The pants size, assuming like most they're 2'' vanity 3. Sizing down for stretch, depending on preference and the type of jeans I'm exact same as oneeightyseven. 30'' real waist, usually buy 28's in most pants, so with DH's 19cm's I size down 1 to a 27. Simple. With APC NS's, maybe I size down two becuase they're cut a bit bigger and the heavier denim might stretch, so 27-26. The only place I see variation on this is your waist to thighs ratio plus some level of how "hard" you work them and how heavy the denim is... just my $0.02
^I bought these off Yoox, they're a tagged 30 and I think they're from SS08. They're a bit loose in the waist now. My other pair of Raf jeans are also a tagged 30 but they're a slightly different cut with a smaller leg opening and are tighter on me all around. The other pair are also slightly waxed, might have something to do with it, these are pretty broken in, the others have only stretched slightly. Just for reference I'm a 28-29 in the waist generally speaking.
ARW and PaulYay, what cut of Raf jeans are those and how did you size them?
Mine are a 32 and they measure about 33.5". I usually aim for 32" in the waist (my tts) but these sit really low so the extra bit helped. However, they are still new so they haven't stretched yet. Got them off YOOX as well so I don't know about the cut.
