Surprisingly flattering for a one size fits all costume! It's a one piece, but you can adjust it some based on how high/low you chose to place the elastic waistband.
I took in the length of the arms a bit to showcase the white ribbon at the end more.
The supplied wig is hilarious, in true Olive style it has a large bun with a wire in it so you can bend it up and straight out the way she wears it.
I added a pair of cheap round earrings painted yellow with nail polish, and brown boots with white diabetic socks rolled down.
It was cute, flattering and very comfortable to wear.
