I'm sure this question has come up before..

When buying kilts(not custom made exactly), they are usually 24" drop.

Wearing the kilt on my hips, the hem comes to bottom of my knees.
Hose, when folded over, the top is two fingers distance to bottom of knee cap. I understand there's a happy medium where it's not too long, or too short.
Is this acceptable, the kilt covering the knee? Or do I just wear it higher, kinda like Grandpa pulling his pants way up?
