This does not look out of place whatsoever, assuming of course one goes back in time 30 years and is an original member of RUN DMC.
There are ~8.2 million people in London and therefore one of them was going to be wearing nasty green trousers, it's simple statistics.
OK, so the sun may be out since for the first time since 1997 but that is not an excuse to dress like a children's TV presenter, unless of course one is a children's TV presenter.
I hope for this gentleman's sake he works on an ice-cream stall or is on his way to a gondolier (that's a gondola driver to the uneducated) convention. However I am not convinced that Brighton would be the most practical location for said convention due to the relative lack of canals. That being said a conference hall would be a better place to host said convention rather than a canal, so I guess it doesn't matter. Although thinking about it would gondoliers even require a convention? I digress...
