When my daughter made the Twirly Dress by Sew Baby for her daughter, I knew I had to make one for Sophie, too.
I found a tshirt with sparkly "gems" on the yoke at Kohl's, and two coordinating prints at JoAnn Fabric. Once the shirt and fabric were washed, it took only a few hours to cut the panels for the skirt and sew the dress.
Sophie loves it! I have lots of fabric left, plus the bottom half of the tshirt (which was cut off to make the bodice) -- so I think I will make her a fancy purse to go with her ball gown.
I'm told she wore it for 3 days in a row, which is really gratifying.
