I always wear socks with loafers. Depending on temperatures, I will wear sheers, thin cotton socks or thin wool socks. Most of my socks are solid.
When wearing non-neutral socks, I will match them to at least one item in my portrait area. Today, for example, I am wearing thin purple wool socks, purple earrings, big lilac scarf, and eyewear in two shades of purple---with black loafers, black corduroy pants, magenta tee, and black pullover.
I like Carla's inspo pics.
