Because fullness allows for plenty of movement in the skirt…….you know, to help while gathering pine cones and such.

**Edited to add:
Many of you posted comments about making this same skirt in adult sizes. I thought I’d post the info here, so more would see it.
If you are wanting to make one in your size, you will construct the skirt exactly the same way. The difference is the piece of fabric you start out with. So let’s say you have a 30 inch waist and you want to dress to be 20 inches long (remember to add extra length because you wear the dress up a little higher)…….you will double the width of the piece of fabric to give it enough fullness to add the pleats and gathered back. And you will also double the height because the skirt is folded in half to give it two layers…..making it a bit stiffer. And then add an inch to both of those dimensions, for a seam allowance.
So you will need a piece of fabric that is 61 inches wide and 41 inches tall.
Then fold it in half lengthwise, just like shown above……and either make it the way I did (with the lost safety pins), or cut a front and back piece. If you cut a front and back piece, make the front piece wider than the back piece, allowing for more room to make pleats.
I don’t have exact dimensions for every size……..because I haven’t made one in every size.
I wish I had the time.
But you try it out and let me know how it goes…..
