For me it is not one single outfit, though I prefer the lingerie look i.e. thigh highs garters, you have to be willing to bend a bit when doing irl meetings, your opponent may want bikinis, or one piece, or bra and thong, or dresses(to rip and shred or just what they prefer) normally (for me anyway) I like a final face to face sit down if feasible to make sure rules are agreed, and attire, and lastly the stakes agreed on, being i do beast fights, we use mock jewelry necklaces to be specific and the loser of the breast fight loses her bra, her necklace and is either straddled and milked (no it doesn't mean your lactating its just the act), face smothered or any other ending agreed on.
