Diana Ross may be the Queen of Disco, but her daughter Tracee Ellis Ross definitely looked like royalty when she shared these incredible pictures of the outfit she wore to her mom's 75th birthday bash on Wednesday. Tracee was absolutely glowing in this sleek and sparkly mid-length Versace dress and matching ombré Louboutin heels. But the real star? Tracee's impossibly feathery bright orange Marc Jacobs coat pulled the entire outfit together and made her look just as glamorous as Diana herself. She completed the look with a sleek bob and a bright orange lip, and we honestly can't stop staring. Such an icon!
