Waist goes first for jeans. I’m a ~33”x34”. My height is largely in the torso so jeans are a little easier, but 36” inseam is generally not too hard to find. I have good luck with Levis.

Getting longer pants is straightfoward enough but man I try to find shirts and stuff and it’s just rough. We have a brand in Canada called Eddie Bauer, maybe it’s elsewhere too I have no clue, and they’re awesome for coats and stuff.
