Short hair on women is always a failure. There are some women that are so hot that they succeed in spite of the short hair, but that's like saying Ben and Jerry's ice cream is so good it'd still be good if you peed in it a little. Hair is probably the one thing that women spend forever messing with that is actually worth the time investment for beauty return.
Anyway, back to the topic at hand. Almost anything that fits right looks great on the lower half. I'd say skirts generally work the best on the widest range of body types though.
And if you want the ventilation to alleviate swamp ass while having the misfortune of being born male you could always wear a kilt. Just claim you're Scottish, no one is going to check.
