from the pic this is what I would do.
First you need to draft or go buy a simple skirt pattern, you can google this and probably find something for free. You are going to need to make a full skirt to attach the ruffled layers to, or to a skirt you already have. You are going to want an a-line skirt (very bad representation of a skirt shape
Make the full skirt per the pattern instructions. Then make the ruffle bits.
You need to measure on your waist the length from where you want the fabric to hit on your sides (so probably about 1/2 your waist measurement plus 2 or 3 inches on each side to make sure you have plenty of fabric to ruffle, noted as "a")
Once you have this measurement, cut 3 or more panels, you will want the bottom one to be the longest, the top the the shortest, so they all show.
Sew on any lace or embellishment and finish the bottom of the skirt panels. You will also want to finish the sides of the skirt as well.
Then make a one inch casing at the waist of the skirt panel. Do not stitch the ends, you will be threading elastic or ribbon through the casing. Thread ribbon and ruffle the fabric to create the amount of ruffles you want on each layer.
Attach each layer to the full skirt. Pin a layer at a time (start with the bottom) and sew along the casing you made, this will also keep the ruffles in place. Make sure the top ruffle is finshed neatly if it will show. If you want to tie it on, you will have to make a half skirt to attach the layers to and then add ribbon to the top to tie it on.
Good Luck, if you have never sewn a skirt or anything like that before it might take some trial and error but I'm sure you'll figure it out - google is your friend
