My parents survived the Great Depression and brought me up to live within my means, save some for tomorrow, share and don't be greedy, work hard for the necessities in life knowing that money does not make you better or more important than anyone else.

Fashion's about extravagance, and everyone needs a bit of that. Carine Roitfeld
I hate the idea of natural. For example, I prefer gardens to wild nature. I like to see the human touch. High heels are a complete invention - an extravagance.
