I had the privilege of testing Kelley's Twirly Skirt and let me just say this skirt has the perfect twirl factor.  The skirt features and double layer skirt (endless fabric combinations from print to solids or both) and a yoga style waistband with built in modesty shorts.  This skirt was a very simple quick sew for me, love it and when a women's size with shorts becomes available I will be making me a pair as well.  Link to bella sunshine is at the bottom of my blog page
