Interview Attire For Hollywood & Other Non-Traditional Jobs

For my entire career I've been dressing up the same way for a job interview in Hollywood. I wear what I call the "publicist's outfit." What is the publicist outfit? An all black suit, black purse, black portfolio, black pointy-toe heels, flats or boots, and a non-black collared shirt with at least the first button undone so it creates a V-neck shape for my necklace to show through.
