As far as honeycombs go, the more you wear them, the more the shipping folds and creases will go away and be replaced with your own marks. Soaking will probably speed this up. As far as keeping the length and/or making it a tad longer, just cold soak it and then while wet, stand on the waist and pull at the legs pretty hard to stretch the length, or just hold the waist and stretch the leg. You get the idea. Lots of people have done this. You should be able to slightly lengthen the inseam and at the very least, it won't shrink any.
