Is it possible to write a style column without invoking Coco? Possibly, but I don't recommend it. Coco Chanel is peerless as an epigrammist of elegance.
Funny, cogent, vivid, memorable, she's the one who first said, "Simplicity is the keynote of all true elegance", thereby distilling your new failsafe dress code in 10 words or less. You're welcome.
Plus, anyone game (and nuts) enough to say a woman who doesn't wear perfume has no future deserves to be quoted.
As a personality, Chanel was clever and driven and distinctive at a time when none of those things was easy for a woman to be. She said if you were born without wings, do nothing to prevent them from growing, and she also said gentleness doesn't get work done unless you're a hen laying eggs.
She took no prisoners, as the hen quote indicates, and famously lavished the bulk of her time and energy on herself and her business. She had an effortless understanding of elegance, but she was also smart enough to put it into the wider sweep of history, which is what really separates the men from the boys in terms of artistic creativity.
