Levi’s Shrink-to-Fit 501s $32.95 On Amazon

I recommend sizing up about 3" in the inseam, and maybe 1" in the waist (or even none).  My actual measurements are about 37×33, I usually wear a 36×34 jean (denim tends to be a bit vanity sized), and I wear a 36×36 STF comfortably.  The waist will stretch a lot – if it shrinks more than you expected, put it on damp and let it dry on you.  Just be careful not to stretch out the knees.
