Try these, they make them in womens as well https://dragginjeans.net/I wear them too. I'm not sure if they would really help if I go down or if they just provide a false sense of security, but I like them. My only complaint is that I have to wear the men's jeans (so they are too big in the waist) because my legs are too long for the women's. I'm afraid to have them altered because I don't the cleaners to iron them or expose them to heat and ruin them.
