I wanted to love this jumpsuit so much. I wear a 10/12 dress so I ordered a large. I wear a large in shirts and in shorts or stretchy pants I usually wear a medium. This thing is so tight in the elastic waist that it won't go up over my narrow hips and non-existent rear end. I put my 4 year old in it and stretched the elastic as far as it would go and there isn't even enough room in it for a second 4 year old. I cannot understand at all how this is fitting anyone unless I just got a defective one. Ill be returning.
