I love these pants! The adjustable under-belly elastic is genius! So comfortable! They stay up great without putting pressure on my belly at all! I started wearing these at 7 weeks when tight wastebands were already a pain and had no issues with them falling down. I am 10 weeks now and can tell I'll have plenty of weeks left in them! I got the small size, I'm 135 lbs and 5'6". My only con is they are a tiny bit shorter than I like my pants, but still by far the best maternity scrubs I've tried. I'm about to order another pair, going to see how the mediums fit. I highly recommend!
