How to cinch the waist of the Patsy overalls
If you think the Patsy overalls are a little too loose around the back waist for your personal tastes, you can add darts at the back. Remember that the Patsy overalls has no opening (zip or buttons) and you need to be able to get in and off. Basically, the waist needs to be as large as your hips. If you have some extra room there, you can add two little darts.
Step 1: Ask someone to help you pinch and then pin the excess of fabric from the back in the shape of two darts. Remove the overalls to check if you can still take it on and off and adjust the deepness of the darts if needed.Step 2: Mark the darts on the wrong side of your fabric.
Step 3: Sew and press your darts. (I dyed the overalls with indigo in the meantime).
