Like other reviewers out there I was a bit disappointed about the thinness of the material over the belly.  Won't do much to disguise a serious outie belly button.  However, it was certainly better than nothing or regular underwear to use under a dress for formal occasions (had two weddings to attend late in 2nd trimester).  I was more impressed with original Spanx (non-maternity) which seriously made me feel & look 10 lb lighter and better.  This product is good, comfortable but certainly doesn't do wonders.  Also wish it had the flap material in the crotch so that you could go #1 without having to pull off the entire garment like my regular Spanx does...
