It's a tutorial for the skirt, but I pinned for the leggings. I bought Addy these in all colors last spring and they are my favorite pieces of clothing ever. Gymboree. Well worth the money, goes with EVERYTHING.
super simple double (or single) layer gathered girlie skirt with an elastic waistband... full tutorial. so so do-able! totally customizable - single, double layer, same fabrics or different, coordinating bias edges or not... yippee!
