Old man butt. While I am in love with the stretchy waistband of maternity jeans, I am not in love with how they fit my derriere. Within minutes of sliding my very disproportionate body into the things, I can feel the material begin to sag. Sure enough, a check in the mirror always reveals a butt that looks like that of an old man (droopy, no shape, pancake'ish). They make those fake bellies that you find in the changing rooms of maternity stores ... maybe I can find a fake fanny to assist me with this issue for the next 10 weeks.
