I know this is a simple project and most people on here probably already know how to do it, but I couldn't find an ible on it. Also you could use this idea for an elderly lady, where she might have trouble zipping dresses or buttoning, a pull up skirt and a pull over top would be much easier.
Dresses and even longer skirts can have this done to them as long as they have an A line sort of shape. This dress to skirt make over cost me nothing as I already had the thread and elastic. Here's what you'll need.
dress that is too small
elastic for waistline
WARNING: This is not a perfection project. It's a quick fix. My sewing machine isn't working so I stitched the top by hand and finished a skirt in about 30min. You could do a more professional job on a machine. I also detailed the steps in the pictures just to make sure it was clear so if you are unclear on a step check the pics or ask and I'll do my best to help.
Step 1: Lay Your Dress Out
Also you can measure your elastic now, I pulled it around her waist and stretched it just a bit. Since you're not stitching into the actual elastic then there's no need for the usual way of measuring elastic. This is more like a belt fit.
Step 2: Make a Waistband
Next you'll need to thread the elastic through the tunnel you made from sewing the top over. When you have threaded it completely through then sew your two ends of elastic together, tuck it into the waistband and finish stitching the waistband down.
Step 3: Here's Your Finished Skirt...
I hope you like your skirt as much as my little girly girl does. This is a quick, fun project a kid could actually do themselves with a little supervision. Also if you're like me and had one too many plates of turkey at Thanksgiving then it might benefit you too. It keeps loved items in use, and material out of landfills, plus it saves $$$
