I bought two pairs of maternity pants back when I got pregnant in April 2011. It was then that I discovered just how wonderful an elastic waistband was. For almost 2 years since I have continued to wear them regularly at least once a week.
It sucks putting on maternity pants when you aren't pregnant and you really want to be pregnant.
Today though, I am wearing the last pair of jeans that I bought that aren't maternity. They are NOT comfortable but I am confident that I will continue to lose weight and they will get better.
