I was nervous to sew this, as it was my first every leotard. I made 2 for my girls, who fit the smaller size range, and made adjustments based on their measurements. The fit was perfect and they were so comfortable, neither of my kids wanted to take the leotard off after checking fit! I love Jalie patterns, I feel I can trust the fit and drafting. The instructions tend to be more basic than a lot of the PDF indie pattern companies out there, but they are straightforward, and easy to follow IMO. Overall, as with every Jalie pattern I have tried so far, this was a reliable fit.
