I used an old knit-n-stretch pattern for this track suit. My daughter is 5 but I made the size 8 top. The pants pattern was for baggy tracky dacks and I don't like them like that. So I measured her waist and the pattern and made them slightly smaller than the size 12mth and slimmed the leg past the knee then made them flair slightly at the bottom. I made the pocket on the front of the top myself and added the Sparkly star ribbon to the top of the shoulders, the pocket and the sides of the pants.
