Hmm, a bag, a watch, a scarf? A little bit of white detail in the shoe/somewhere else?
Like in this Angie's stunning outfit: she is wearing a black suit with a pastel blue shirt; but the watch and the bag are white, the shoes have more white than black and the shirt has a white collar:

Edit: He he Angie, this is too funny! We typed at the same time and referenced the same outfit of yours!
