Got the Wonder Woman bib costume for my 5 month old for Halloween. And she looked adorable!!!! I highly recommend having clothes under the costume/bib. I put my little one in a white long sleeve onesie, red pants, and white socks with little gold sparkles/stars on them. All stuff I already owned. I also had a dark blue head band (yes, I know, it's suppose to be gold) and my friend make a bow to go on it with the Wonder Woman symbol. With the bib and the things I owned it made it look like a custom made costume.

Anyway it's a great costume and your daughter will look cute and adorable. She'll stand apart from all the princesses, ladybugs and farm animals.
