I made a post on here before about a fight my sister had and mentioned the potential of her fighting my girlfriend. They both hate each other and I've always wanted to see them fight, I really don't get along with my sister so I would love to see my girlfriend beat her in a fight.
They're both the same age (23) and the same height, their weight would be similar but I'd guess my girlfriend is a little heavier.
Who do you think would win this fight considering all this and the emotions going on around this fight also?
The first 2 photos are my sister and the bottom 2 photos are my girlfriend.
