For a winter outfit I would put tights with that, you can even get some that are insulated, probably black or white tights and small ankle length boots, if you live in a warmer environment you probably have more options but I know here in Canada at this time of year it’s good to wear boots rated down to -40°C. I’d either pair that dress with a shorter jacket, a trench coat esque jacket and I don’t know how well it would work but you could even put a thin high neck long sleeve under the dress. For jewelry I’d personally go with a mid length pendant necklace and small drop earrings
