I bought these when I was about 16 weeks pregnant. I didn't want the kind of underwear that pulls up over my belly. I had them last time and just didn't want them for this pregnancy. These fit so nice and are very comfy. They don't pinch my belly anywhere and pretty much fit under the belly at 27 weeks. I haven't made it full term yet but I will definitely buy another set. These are NOT cotton type panties so if that's what you are looking for, this is not for you.
