Luckily I read the reviews and ordered a size smaller. XS fit perfect and looks amazing! I'm 143 lbs at 20 weeks, 5'3", and size small pre-pregnancy, but I ordered the XS. Like most jeans, I do have to roll these up, but that's just because I'm short. Shipping took a couple weeks.. These jeans look and feel better quality than many of the $50 maternity jeans out there, so I am thrilled. The belly band goes all the way up so far, and I do have a large belly for 20 weeks due to having such a short torso. I wouldn't mind if the belly band were a bit longer for when I get bigger, but I'm pretty sure it'll still be comfortable. I honestly wish I found these sooner and I'm definitely going to wear them to full term and post pregnancy as well. These are a keeper!
