Well I guess it depends if your asking street fight or arranged rule style. Arranged like a breast fight I always take losers bra . As for a rules cat? If hair pulling is allowed ( usually is) you take hair with you from pulling it, same as a hair fight. As for real catfight , most I have taken is hair from loser , there was a fight I had as I swiped at her neck my nail caught her necklace, tore it off so after she was done I took it. But as for arranged rule fights what the winner takes is often discussed prior .
