So I'm going to go try on a pair of xx-007 and xx-010 both unsanforized and slim straight.
The general consensus seems to be get the thigh measurements right. After initial soaks I should expect roughly -1" in the waist, -1.25" for the inseam, -0.5" in the thighs, -0.3" for the knee/leg opening. Thighs don't stretch much, but the waist will.
That being said. If it fits well at the store, should I size up to compensate for shrinkage?
