Given the choice I always chose the trousers.
Why? Because I got sick of passengers trying to stare up my skirt on the jumpseat, it made it easier bending down to carts for meal delivery, also standing on seats to get in to lockers no-one could cop an eyefull, and of course freezing weather in to international ports and cold galleys on long haul flights was horrible in a skirt.
Primarily though my choice was safety. Even in the mock-up my legs would heat up on the slides and that was in jeans and overalls. Imagining nylon stockings glued against my skin in an evacuation was enough to put me off the skirt forever. Having been involved in an emergency evacuation I was glad I made the sensible choice.
I know the skirts look nicer, but I think every airline should give their crew a choice of attire.
