I cut off the bottom of the tank just below the arm pit. Leaving the most length possible.
Stitch a basting stitch around the top of the skirt. You may need to gather the skirt a bit before sewing on the waist band.
For the waistband I had a piece of knit that was a perfect match . I measured my Little Missy's waist and subtracted 1 inch. Knit is really stretchy. I cut my fabric 19 by 6. Fold your waistband in half lengthwise and right sides together. Short ends together. Stitch. You should have a circle for a waistband.
Fold the band in half to make it 3 x 18 round. Pin the band to your skirt. Giving the skirt and even gather if your must gather. Stitch around with a knit stitch. securing the waistband to the skirt.
Here is how my skirt turned out.
I think it turned out so cute. She loves it! I think it makes her look so grown up. Fun and easy for the summer. Great for the beach, church or a day of shopping. Head out and find a tank for your Little Miss.
