Jolt, I use the static guard stuff, if I have to, but I went to a "real" lingerie store and bought a couple of slips that are of different materials and they work. I actually have a pair of what my mom used to call "petit pants." They are like shorts, but a slip. They are very short, so I can wear them with my shorter stuff.
I don't wear long skirts, so I can't do the knee sock thing. But, I couldn't do that anyway. I know, I'm weird. I used to wear knee socks and short skirts as a kid, but I think I'm too old for that.
I usually only wear black hose now, or grey and they don't look that different than tights. Most of my skirts are black or very dark. But, I think I mostly wear tights, too.
