It's a fair enough generalisation in my experience. Fair enough in what context? It's certainly a patently valid generalization, but it's still a generalization and, perhaps more importantly, is one that has no obvious and direct connection to being female. Had the OP's study limited itself to women who self-identify as being feminine and/or wearing skirts, or at least measured that, I wouldn't even question it.
