I got this in the 2xl so the tummy part would not be tight. It is very cute and I love that there is lining on the inside. On the back there is a long zipper that goes all the way to the waist area. I have a bigger bum and wiggled a tiny bit to get in the dress that way. It was difficult to get such a long zipper up my back afterwards so you will need help. I suppose I can also slip the dress over my head but my shoulders are wide and I would need help pulling the dress down. I am returning only because even with Spanx on, the ruffle sleeves land right where my waistline is and brings more attention to the big belly. I most likely would not wear the dress for that reason. Otherwise I would keep it!
