I am giving you the measurements I used for a girls waist size 5/6 although the length of the skirt is more like a girls size 7/8.
If you need another size….you need to find a length measurement (waist to knee) and then figure out how much of a waistband you want above the ruffle. I made my finished waistband 3.5 inches above the ruffle (plus 2 inches to fold over for the casing), so the cut height is 5.5 inches. Your ruffle should stay the same, unless you are making the skirt for a teeny tiny girl, then you might want to cut it down a bit.
Main Skirt Fabric—45 inches by 14 inches (for size 5/6)
Waistband Fabric—45 inches by 5.5 inches (for size 5/6)
Ruffle Peplum Fabric—-90 inches by 10 inches (for size 5/6)
1″ elastic—size of waist minus 2 inches (20 inches for size 5/6)
And here’s what you do: (The pictures are from my prototype…so ignore how short the ruffle is….;)
And you have yourself a cute and trendy ruffle peplum skirt!
A couple of other ideas if you are wanting a skirt for an older tween/teen:
*I think I might make the skirt below the peplum a straight skirt (waist plus 2 or 3 inches) and then add the ruffle. I think more of a straight skirt would be darling on an older girl.
*Or, you could make the front a flat front skirt…and just add the elastic in the back.
