skirting the issue

I've been avoiding skirts. Don't ask me why. I've tackled much harder projects lately. I just have a hard time estimating elastic, and wish I had a model here in the house. So, I measured on my son and came up with this all on my own.
I think it might be a little wide & a little short, but I'm not quite ready to ask him to try it on so I can see for sure. Anybody know any size 3/4/5 girls who want to try?
The top layer is a red, pink, gray and white corduroy full of flowers and swirls. I used it for a jumper last year, and had enough still in my stash to whip up this skirt.
The bottom layer is muslin (so it's not too thick) with a gray corduroy ruffle. I can picture it now... tights, boots... oh so twirly and cute!
