Your pants are not proportionate. The elastic waist band is very tight, while the rest of the pants are roomy. I couldn't wear these comfortably on a plane, and I have a flat stomach, no kids. Also the tank top that comes with the set - is very cold to wear on the plane. This set didn't work at all for me. I coudn't return these in 48 hours -- because they arrived when I was traveling. I could only return them for an exchange. You do not list proper sizing on your site, unfortunate.
