clobber

Clothes — particularly the outfit you've put on for going out. Heavily used in Scouse but common across British English. Often implies decent, fashionable gear rather than any old rags. Liverpool's casuals scene basically ran on the word.

To hit someone hard. Verb form, separate sense — to give someone a clobbering means a proper beating.

Your clothes, your gear, your outfit. In Polari it sat alongside 'drag' and 'clobber' for what you put on your back. It's one of the Polari words that survived into general British English — plenty of people say 'get your clobber on' with no idea it ever had a coded life. Plain, useful, and very much still in circulation.
