I've been looking for a nude mod for Natalia in Resident Evil Revelations 2, but looks like there isn't any. I'd make it myself, but I've zero knowledge of 3d modeling. There's a costume selection menu, so there should be potential to make different costumes for her and a nude one too. I found a few non-adult costumes from residentevilmodding forum like this Zelda one, but more NSFW costumes could be so much more fun :D I currently love her official Lottie suit costume:
