As everyone knows, there's a current trend to wear your trousers or jeans so that they are dragging across the floor. You may well be wearing a pair yourself. Amazingly I've never seen anyone trip up in them, so there must be an art to wearing them, or rather walking in them.
Long Trousers One
A nice example of the long trouser here. I think they were some form of track suit bottoms (I'm sure there's a trendier name from them, my boss was shaking her head at me last week as I had never heard of Converse shoes - but I digress), as you can just about see a zip up the back of them.

This guy was wearing my personal favourites of the week. I love the particularly attractive way they all bunch up while he is sitting down in the classic "bloke on Tube with legs wide apart" way.
