The J. Crew catalog came in the mail this week. Flipping through, I saw this skirt, and thought I could probably make something like it myself.
I used some black & white seersucker. (this pic is not the best - I'm all wrinkled from wearing it all day and too lazy to bother ironing and retaking the shot) I ended up not doing a drawstring and making it more of an a-line. And though I was shooting for avoiding maternity wear (which I am good at inadvertantly achieving) I used a thick piece of elastic for the waist that I had purchased for making maternity pants but never ended up using.
It's nice because you have all the comfort of an elastic waist band, but because it's so thick, it sits up without having to be cinched like thinner elastic. I think it gives it more of a polished look.
