dunno, but i think the 31 should do. the thighs will shrink a bit & won't stretch back out unless forced to.
the waist band construction is same as trousers, so it's just a quick fix__ in case you need them altered.
re-posting my 31s for comparison.
you probably have bigger thighs than me cuz i don't have "thigh issues" even on slim cuts
u/thigh = 12" = measured from 1" below crotch ***post double hot soak
