I love every piece! :) My only problem with it is the layering of the sleeves. Roll them up once or twice together so they look like they're the same garment on the cuff. Somehow that always brings a color palette together.
Those are great tights but they don't go here. I would say just don't wear tights and keep the cream lace or switch the tights for solid black and switch the tank for a solid white color.
i like it, but there's too much going on, button up the dress or get a tank in the same colr palet, because the dress and the cadigan look fantastic together. lose the tights, please.
