>>2474077I think it's just fandom taking something and getting out of hand. He does have a slightly protuberant chest in some outfits, but so does Ignis. And besides they're not even close to the level of literal breasts fanart likes to do. Maybe it's because Prompto is the designated super-uke and it makes him look even more "feminine" or something like that.
