I'm on a short conference for work and by chance today wore a more busy version of outfit #1. This is actually a combo (cropped pants, long cardigan) that I've been wearing for at least four years and I still enjoy it. But wearing with loafers is new.
My version includes a scarf and patterned socks because it's cold here! I will take the scarf off in a few hours.
I prefer long cardigans to shorter ones but I do own several short ones, too, that I tend to wear as tops (as in the third outfit).
