I was reading the latest Game Informer magazine and in the same vain for "their appearance was changed to fit a younger audience" was mentioned about Claire and Jill for Mercenaries/Revelations. I kind of stared at the letter that was sent to them about it and was like "Dude, Claire's outfit is actually the original Code: Veronica outfit. They just updated to look more modern while keeping a similar style and appeal to the 90's."

Jill's outfit in Revelations, though, looks A LOT like her battle suit in RE5. I will give them that much, but I don't think it's to "appeal to younger male audience." :|
