If you're having trouble with your belt curling, there are a few things you can do to fix the problem. First, make sure that you're using a belt that's the right size for your waist. If your belt is too big or too small, it will be more likely to curl. Second, try tightening your belt so that it's not too loose. A belt that's too loose is more likely to curl than one that's snug. Finally, if your belt is made of leather, you can try applying a small amount of leather conditioner to it. This will help to keep the leather supple and less likely to curl. If you follow these tips, you should be able to stop your belt from curling.
