Here are two random outfits which both happen to involve black leggings. Below, a beige and brown coat with a Fair Isle-ish pattern (and some black panels, I think…) is worn with black and beige cork-soled sandals and a black scarf.
…while here, a black coat is worn with a fuchsia scarf and beige platform-heeled shoes that seem to be made of netting. I think the leggings below may have some rhinestones or studs on them, but I am not sure. Either way, the leggings look great with both outfits.
