From my experience, owning pairs of Energie, PD&C, and Diesel, I can say that Energie runs true to size, while both Diesel and PD&C run a little large. For instance, I am by most standards a 32, however my PD&C jeans are size 31 (plus they stretch..) and my Diesel vary between 30 and 31. The Energie jeans I own are 32, and fit perfectly; no stretching either. If you're in a dillema between two sizes, I'd recommend the one thats slightly tighter, as opposed to the one that's a little loose. Jeans tend not to shrink, instead I've noticed them to strech a bit. PD&C jeans are really cool, they're my favorite pair, although they won't last as long as say a pair of Diesels, which will last forever, like a pair of Levi's. IMO the men's Seven jeans look too much like the girls version for me to buy them. I also think they overdo the washing, and damn, are they lowriding.
