I have never met Christia Freeland but from what I have read about her, before and after she entered politics, I have gained a lot of respect for her.  My impression of her is that she is so secure in who she is and her abilities that she didn't even think about the pink dress and pearls beyond "I think I'll wear that pink dress today, with pearls".  If questioned or challenged about her choice, she might have responded "I really don't give a rat's patootie".
