I have a costume that is just slightly too snug around my waist. It a basic circle skirt, but it has a zipper up one side as well as detailing the would be hard to remove. I don't know much about sewing, but I was wondering if I could apply this
tutorial to the side without the zipper just to give an inch more for my waist. And would it unbalance the skirt if I only inserted a triangle on one side?
If anyone has any other suggestions I'd happily listen as well.
