Using these stocking suspender straps is easy. Just put them on like you would any other suspenders, and they'll hold up your stockings securely. When choosing a size, make sure to check the size chart carefully because different suppliers and brands have different size standards. For maintenance, you can hand - wash them in cold water with a mild detergent. Avoid using bleach or harsh chemicals as they can damage the spandex and nylon materials. After washing, let them air dry. Don't wring them out forcefully to prevent stretching. With proper care, these suspenders will last you a long time and keep you comfortable during your daily activities, especially when swimming.
