Girls tights

Hello, I’ve been knitting for a few years and I’m looking to make a set of tights for my daughter, but I can’t find a free pattern anywhere. I have knitted two long socks for her in the past, but they end up falling down. does anyone have a pattern or tips on how to turn the long socks into tights?

Ravelry is the best place to look for something like this. I don’t know what size or the age of your daughter so here you go…
