Would you like separate clothes layers ? (Instead of top and jacket/sweater combos)

I don't expect this would ever come to TS4, but they really should consider it for TS5. I agree with who brought up Saints Row 2 - I think it worked really well there. It allowed for a lot of versatility (and it had lots of colour options instead of a couple of swatches). That game also has a gender slider, which is something else I'd love to see.
