You need the MESH file.
I took too long to get myself organized and so these sweaters that were meant to be uploaded before Christmas are finally here. I am so sorry about that. My favourite one of them all is the one that says *Naughty or Nice*. that one just totally cracks me up. I just love sweaters, cardigans or jumpers, whatever you choose to call them and these are pretty darn cute.
I do have all of Sims4 Expansion and stuff packs installed, but I can't remember which game these were made from.
Happy Simming Everyone!
