I was nervous that this wouldnt fit me since I was 8 months pregnant but if stretched well and sucked everything in at the same time. I got so many compliments on my mermaid costume. I am looking for another excuse to wear it.  Depending on how tall you are, be prepared for a lack of movement if it doesnt start glaring past your knees. Length was perfect for me. Im 52 and wore it up to my bust.
