|Please ignore the dingy onesie. |
This was a trial run with one of the boys' old onesies!
A lot of onesie dresses cut off the bottom part of the onesie, but I left mine whole so that I could still snap it around her diaper. That way it won't ride up when she wiggling around or we pick her up. I just hemmed a rectangle of fabric, gathered it, sewed the side edges together, then sewed the skirt onto the onesie. Then I sewed a purple tube of fabric and sewed it right over top of the ruffle (mostly to hide the raw edge of the ruffle). I thought about doing a whole tutorial, but didn't know if anyone would be interested. If you want more detail, let me know. :)
