Dancer legwarmers (i.e. LONG)?

I keep seeing legwarmers but they all look like they go up to the knee when pulled straight. I want some like dancers have, that go to midthigh. Anyone know of a pattern for those?

Not sure if this is what you mean but I will be using this pattern to make some for my daughter. :thumbsup:

You could maybe use this pattern and not make the feet part…
