Why wear her? Because she is not taking any nonsense today.
What does she do? First she slams her purse down on YOUR desk, whips off her mink, and flings it at your face. You work for her, not the other way around. While you struggle with a coat hanger, she swans into her office and loudly declares that she's never known a fresh cup of coffee fail to be on time, unlike you. (This despite the fact that you're half an hour early to work every morning, smile fixed precipitously in place.) You're desperate for a cigarette and twelve mai-tais, but it's only 8:30 in the morning. Is this what Katy Gibbs meant by success? Welcome to the big time, kiddo!
How do I feel? Invincible, imperious-- so of course I'm wearing Cabochard. Now take a letter and be quick about it. What do I pay you for?
