I started wearing this in my first trimester to help keep my unbuttoned pants up, and it worked very well. Now I'm at 25 weeks and I'm still wearing it as sort of a belt for my maternity pants, which aren't loose, but don't like to stay all the way up on their own. It works well for this, too. The only complaint I have is that I have to rearrange it quite a bit because I do a lot of standing/sitting during the day, and it tends to roll up on itself. Other than that, it really helps to smooth out bumps created by unbuttoned pants or other layers. Keeps my pants up, and that's what it's supposed to do!
