My niece Isabelle is a big Fancy Nancy fan. And I mean BIG. She can recite all her Fancy Nancy books by heart, and all her outfits ('ensembles' if you're fancy) must include a glamourous feature. So my non-sewing sister bought some gorgeous Fancy Nancy fabric on Etsy and asked me to make something FANCY!
Isabelle wears it constantly. I have some fabric left over so I think next I might make her a dress to match.
My only regret is that I didn't find a pink feather boa to go with it, because that would be way more fancy.
If you've been living under a rock and don't know about Fancy Nancy, here's the link.
Look it up - your little girl will love you for it. The picture books are divine.
