Note that while "has got" is not completely incorrect (at least in spoken English), an English speaker would be more like to say "is wearing" if they mean the person is wearing it right then or just "has" if they mean the person possesses it (but maybe it's in their closet at the moment or the speaker doesn't know what they're wearing right then).
Also, "trousers" is somewhat uncommon in American English. We'd say "pants" -- but "pants" does mean something different in British English so it's up to you which you choose.
