Thanks to my sister-in-law, I acquired a long-sleeved knit navy shirt. The front side had a screen print, but there was just enough fabric on the back side of the shirt to make a size 2T ruffle pant, from the pattern I downloaded on youcanmakethis.com. It's a Jocole pattern with multiple sizes for these everyday ruffle knit pants.
Here's go-around 2-I made a pair of capri (without the ruffles) for my 5-yr old daughter. If I do it again, I'll need to enlarge the pattern slightly, since she's more of a size 6.
I cut the length so the natural hem of the shirt would be on the pant. Worked out great! Happy with how they turned out. I'm having such fun making these clothes for my girls!
