matching jewellery for clubs who else

so we got these matching little silver bands not weddin rings, separate thing... only wear em on club nights or to meets. its our little code, like puttin them on means we're officially in LS mode for the night. weve been doin it for like 4 years now and i cant imagine goin to a club without slidin it on in the car park. anyone else got matching bits you only wear for the scene?? bracelets, necklaces, rings on the right hand?? curious how others mark the switch...
