I ordered the black belly band in a size 2 (my pre-pregnancy size was a 10/12) and it fits just right! I am extremely pleased with it!! I am only 14 weeks along, so I slide it on inside-out, pull up my jeans, and then fold the extra band over my unbuttoned jeans. My jeans stay up and are comfortable- they feel like maternity jeans! The only issue is that it's time-consuming to repeat the folding process every time I use the restroom... which is quite often these days :) But you give & take, right? I recommend this product to all mommies-to-be. Purchase the smaller size, if you are on the fence of which to buy. When my belly gets bigger, I can wear the band full-length over the baby bump and still feel comfortable. After Baby comes, I can also wear it over my belly while breast-feeding, for extra modesty! So you get your use out of it, for sure. I think the white band would show your unbuttoned jeans, so either order a darker color, or wear thicker and longer shirts over the band (I do this anyways, so it's ok for me.) I love the length of the band and it looks like a long tank underneath. I just love this band so far! Worth the money to help me wear my pre-prgnancy jeans and skirts even longer! God Bless all you mommies and future babies! They are such a blessing from the Lord, and I am so excited to have my first!
