When I was pregnant with my first seventeen years ago, being pregnant meant one thing in the underwear department - grandma panties. I even specifically remember a very vivid scene from a movie during that time where this beautiful and pregnant woman had her husband slowly fold up her cute prepregnancy underwear and stare horrified at the huge cotton panties they were replacing. Speed ahead to today and what you find everywhere is a variety of different types of panties for pregnancy, but the one shocker is the sheer number of maternity thongs that have crept up. (Pun intended.) Apparently the fashion sense is that if it's going to ride up, you might as well put it there yourself. Where do you fall in the great maternity panty debate?
