During my recent trip to Seattle I stopped by my favorite nail bar, Butter London. I love the polishes (and the packaging and names, let's be real) and they always do such great manicures.
This trip I selected Black Knight just out of curiosity, and I loved it so much I had to take a bottle home with me. It's black (obviously) but has every color of the rainbow in glittery bits that reflect differently depending on how the light hits it. It's sophisticated yet rocker chic. Perfect.
