Perfect lenght for me (I'm 5'7") and the waist band is very comfortable.  They don't seem like they would stretch very much but I was pleasantly suprised at how great they fit.  Right between the jean waistband and the panel are some buttons with elastic that you can tighten to give a tighter fit early on and loosen later in months.  It's a great idea to make the jeans more transitional.  I love them and they have cute pockets on the back while most maternity jeans are fairly boring.
