I've heard lots of good things about Jalie patterns for making dancewear, so I picked up Jalie 3247, Crop Tops and Shorts in 24 sizes. That link will take you to the pattern, being sold by msbonnieb on eBay. Jalie is a Canadian company, and they don't seem to have a lot of retailers in the U.S. It was easiest for me to go the eBay route.
Here is a picture of the pattern mostly laid out on my sewing table. I wish this would have come in more than one paper piece. As you can see, some of those larger pattern pieces are huge, and having to maneuver that large sheet of paper around got a little difficult.
And above you can see how the shorts turned out! She likes them, although they are a little low in the rise for her. But she wears a leotard under them, so it's not too bad, and I think she's gotten used to them. I have enough material left over from making the girls bathing suits, many years ago, that I can make several pairs of shorts for the Dancer, making the pattern a pretty good investment! I have the next pair of shorts, the other pattern view, almost done; I just need some red thread for the hemming and attaching the elastic. I hate going to JoAnn's anymore, and the smaller sewing stores don't always have convenient hours. I may just have to mail order. I'm a little unhappy with having to do that for such a small purchase, but those red shorts have been almost done for quite a while now!
