Why do NPC Sims get a wider, better selection of costumes than our played Sims can choose under "wear costume?" Is there any way, mod or vanilla, to add more outfits to the "costume" category?
I put costumes in the only party slot, and now every party is a costume party. Which is kind of how my real life works too. I haven't thrown a non-themed party in... ever.
It does mean the night clubs have a different dress code now, but that actually has become amusing over time so I live with it.
