The flexible waistband allows you to adjust the length. Perfect for petite people like me who wear heels and can't usually handle long inseams without tailoring. I also happened to be on the one-wine bottle a day diet on my recent trip to New Zealand. An elastic waistband helps. ;) Consider this a pro or a con, but they will most likely work if you are in your first or second trimester.
And the price...$69US dollars? A steal...Available at Zappos
