I've asked the original creator is they could give me a hand, but thought someone on here would be able to help in the meantime. (I dabbled in S4S and Blender with some success, but limited given by restricted knowledge.) Only problem is it's for children only, and I'm simply not skilled enough in trying to mod the file further to turn it into an adult compatible costume. I downloaded this costume mod from LoversLab courtesy of 'Elsalovescocaine' which simply puts Sims into a Meowth costume from Pokémon.
