Looking for separates to pair with a suit or on their own? Look no further. A smattering of great options from Anthropologie, Boden, Club Monaco and J. Crew.
If you feel like adding a skirt to a top go with a basic pencil skirt or a fuller skirt in a basic black wool, and throw on some tights. If skirts aren't your bag all of these tops would look amazing with black slacks, cropped or full length, OR for an added dash of luxe throw on some tuxedo pants, like these here, from Zara.
The bottoms above all pack a punch on their own so I would pair those with a basic button down or a nice silk top in a basic shape, think T-shirt shape, like this one from The Outnet and some patent leather shoes.
Add a bright lip or a statement necklace and you are holiday party ready!
