Nylon is a strong, yet lightweight fabric that has a stretchy quality, so it's well suited for lingerie. It's easy to clean and care for, but can also easily become wrinkled. If you find your nylon lingerie is filled with creases, don’t immediately pull out the iron. While it’s usually okay to iron nylon fabric, it's possible to melt it if the iron is too hot, so it's best to try a safer method first to remove the wrinkles.
