Same drill as before, start with a onsie and fabric scraps (by the way, I didn't buy anything for any of these onsie makeovers). I cut the onsie off about 2 inches below the armpits and saved the bottom. Because I was using what I had, some of the strips weren't very wide, so I didn't want to waste width with a hem. Instead, I just serged the edges. After that, I ruffled the top strip:
The top strip then gets attached 3/4 of an inch above the bottom of the onsie piece:
I attached the rest of the pieces, in overlapping tiers, to a piece of white knit. I left about 3/4 of an inch of the knit uncovered at the top.
Then I took the edge at the bottom of the onsie piece and the top of the tiered piece and zig zagged them together.
I didn't worry about right sides being together, since the seam would be hidden by the top ruffle. And then:
Doesn't she look like Little Miss Muffet?
For next time: I didn't think about making the strips for the ruffles longer towards the bottom this time, which is why I got more of a bell shape than an a-line.
