I believe it has been confirmed several times by now that Cheerleadra wears shorts.
Even if I'm mistaken about it having been confirmed before, it's been confirmed now.
Granted, that's a fantasy image, so maybe it only confirms that Luke THINKS she wears shorts? Or that everyone knows she wears shorts after all that flying around?
I regret thinking too much about that and wish I wasn't pretending that was the reveal on this page, but it's too late now, I've committed to the bit.
