I didn't take the time until I was about to write this to ask Jackie how she'd gone about this, since I knew she didn't have a pattern. So I've just gotten off the phone with her. I didn't know if she'd taken the suit Amy had used in the past couple years or if she'd just taken a tank and pair of shorts that fit Amy, and gone by those. She said she had the suit out to look at, but mostly went by a tank and shorts that fit Amy snugly, just as my mom had taught the ladies to do in the sewing class last Spring. This is also how I was taught to make swimwear. Only later did I develop and use patterns.
Jackie said she'd used a pair of knit shorts from Target, and an under shirt type tank. Jackie also viewed a picture of the girl's ice skater suit to get an idea of how full the skirt was to be. She did a really great job of recalling all the sewing steps, and her work looks very nice! The belt is different than I've seen before. Jackie said Amy had been given a pair of swim bottoms at one point in time which had this scrunching effect. Its cute. I was pretty impressed, and so was my mom.
