Rubie's Costume Pumpkin Pie Costume

I'm worried this will be too big on me. I am 5'5 and wear a size 4- 5 in dresses. Will it fit?

Is it a dress or have closure at the bottom, just wondering how easy it is when you need to use the restroom.

Will this fit ? I’m 5’10 about 190ish

Will this fit me i am 5'6 5'7 and plus size women.?
