Ngl..the og female is pretty but the dress doesn't suit her naive self.

Exactly I don’t know why they decided to be petty and not even match her color pallet

Because the prince wanted to see how eris would react. I'm sure he knew that his fiance would wear that dress and he probs got a copy to try and embarrass both the girl he was with and his supposed fiance. Truthfully the prince is something that should be dumped in the incinerator.
