I used the toddler version of Rae's Itty Bitty Baby Dress. Super easy. Wait, back up. Super easy except for the piping. I found out the hard way that I'm not a piping kind of girl (at least not for now), so I connected the bodice and the skirt with a simple band, and then top-stitched it (I heart top-stitching).
I'm happy with how it turned out, although next time I might modify the fullness of the skirt (it's a little poofy, no?).
What do you think?
