Leggings are great for so many occasions, but unfortunately, the elastic in them can wear out quicker than the actual garment. This is not only frustrating, but it can also lead to a lot of waste. Luckily, there's an easy fix, and it doesn't require any sewing. Just take some shoelaces, or two if yours are short, and tie them around your waist. Then, just fold the top of your leggings over to hide the laces, and you should be good to go.
You could also fold your leggings down before you tie the laces and just fold them back up, but either way works just fine and can save you some money.
