Trendy Tummy Maternity Coco Maternity Women's Evening Formal Long Gown

I have never had to zip into a maternity gown, it flows over my belly but does not zip all the way. I need to get it taken out. I am very small frame 5'1 and size two before pregnancy. I got a large because I will wear it at 9 months.

Very pretty dress. 17 year old daughter wearing to prom. Ordered size medium and 27 weeks pregnant. Fits well. A little long but she's only 5'2 130 lbs. May get altered to reduce length or just wear heels.
