I love the construction of the waistband with the rows of elastic in the back. You can also tie the sash in front or in back.
Happy Birthday Girls! I hope you love your skirts! (Thanks for the perfect opportunity to sew something!)
ETA: Just to clarify - I did not make Momo's skirt. I am hoping to post a picture of Kailani and her BFF in their matching skirts but do not have permission yet to do so.
