Good nude tights?

I don't want american tan of yore
I have a really nice knee length dress that I want to wear to a party soon, but I am very self conscious of the backs of my knees thanks to a nice set of stretch marks I gained there when I was pg. They're silvery and faded now, but pretty deep. I don't really want to have to wear opaques, but I don't have the confidence to go bare legged. Is there such a thing as nude coloured tights that will hide a multitude of sins? I thought maybe even a very teeny fishnet pattern might distract from it?
