WranglerWrangler Boys' 13MWZ Cowboy Cut Original Fit Jean

Do they have a adjustable waist?

what is the inseam length of these jeans?

I’m a 5’7 female, petite body built with long legs. I have a 23.5 waist, should I get a 14 or 16?

Need a waist size 42 and an inseam 32 what size would this be and why are there comments about anything on these jeans stretching?
