I've been wearing one pair of my non-maternity jeans on days when it's not a thousand degrees with a million percent humidity (please allow for slight exaggeration in all weather-related comments) and boy, those buttons and zippers and all certainly are time consuming. As opposed to the pull-on nature of maternity wear, I mean.
Maybe I should just switch to all elastic-waisted pants. That'd be good for my look, I'm sure. It would save me precious seconds in my frantically rushed bathroom visits, however.
