I have a daughter named Stella, but this is not her!
Iris is wearing a size 6 years Stella skirt with about 3 inches added in length. This was my most finicky project to date, but it is all sorted. Iris is 7 and a half years old, but the size 6 is really loose at the waist, so I went back into the waistband afterwards and added an elastic.
In addition to the zipper, this skirt will stay firmly in place now. The fabric is some upholstery weight cotton that I bought at an antiques store attached to the market.
They were having a big sale in January and I picked up some interesting fabric.
