OK, here's the pants. I used the tired ruffled pants from YCMT.com, and the instructions looked really easy. I started on them Sunday morning, and I thought I would be finished with them by the end of the day.

I just finished them yesterday evening. The first ruffle was easy to put on, but the middle took me a while to get on. The third one at the bottom was a real pain in the neck!
I started with a pair of pink shorts from Old Navy.
The shirts they are wearing are only a temporary piece until I get the shirts made to match. I have to get the Wiggles outfits finished before I start on them though. The matching shirt will be made from the same fabric as the middle ruffle (blue background with pink and purple stars).
ETA: The one in the big, red flip flops is really confident that she is wearing those today.
My plans and her plans aren't the same.
