I normally wear cotton batik trousers bought from folk festivals, which are that sort of "one size fits all" that actually means "four inches too long for all normal people." I've several times almost tripped over them. But they're not as bad as the ankle-length skirts that I wear. If you crouch down and manage to stand on your skirt before standing up again, you not only fall over, but your skirt tends to come off, too. This is quite embarrassing when it happens in front of a building site when you're getting up after slipping on the ice.
