Expand piercings
I really like that the Sims 4 already includes nose piercings but I think there’s a lot more potential for expanding piercings and making them more customizable. It would be great to see a wider range of options like stacked ear, piercings multiple lobe and cartilage placements, and the ability to mix and match different earrings in one ear instead of just single presets, adding more nose options like hoop ring septum variations in different sizes would also make CAS feel more realistic and expressive. It would also be cool to include gauges/scratched ears, asymmetrical, piercing styles, and more freedom to lay your jewelry so Sims can have unique styles instead of limited slots. Overall more piercing variety and customization would add a lot more personality and realism to sims creation.
