Hopefully she'll be able to wear it this summer. The bonus about this kind of dress is that it can be used as a shirt as she gets older.
If you've never sewed clothes before, it's worth trying out. I also made her a matching hair bow and a little stuffed animal based on this tutorial from Ruffles and Stuff. It's crinkly inside. I hope she liked it! She was a little overwhelmed with all of the gifts and wrapping paper at the party.
