I tend to have a problem finding anything in the right sizes...  I am 6'3" and 190 lbs, and tend to wear a 34x36 in pants or a Large Tall size for long sleeved shirts.

After trying a few pairs of various 5xx cut Levi's I realized I had found a brand that carried more 'unusual' sizes.

These 559 are not as casual as some "relaxed" fit pants I have tried... they do not make me feel overly casual.

I also have a few pairs of 514s and enjoy them as well, although they are definitely a little slimmer in the thighs.
