I used a Linen/cotten blend. It looks so cute and peasant-y to me. Peasant-y is a word, right?
The skirt was me experimenting without a pattern for a simple gathered skirt. It worked out just fine after one round with my seam ripper. (I tried to make the waistbad before I sewed the side seam together. I quickly realized I couldn't insert my elastic if I did things in that order.)
