Gov. Nikki Haley visited a Bridgestone tire plant last week. She wore black and white: (http://youtu.be/gSguCfO4HF8)
This much shine is very difficult to pull off in the daytime, and I don't think it works here.
She made a valiant attempt at dressing down the blazer with a plain black top and her customary cross, but all we see is the sheen on the blazer. In fact, the sharp color contrast between the black and the white makes the jacket stand out even more than it otherwise would. If you're incorporating a shiny or sparkly piece into your outfit, a tone-on-tone color palette will do a better job of balancing it out.
