This weekend I made a onesie dress with this tutorial. The tutorial is completely customizable for size and style - super fun. The onesie is completely intact under the skirt, so it will fit nicely without any bunching.
If you think the skirt looks like an old sheet, you're right! This was a test project so I didn't want to "waste" any of my other fabric. As it turns out, I really like it.
More to come!
