Channelling French Chic

From black cat to a feline of a different nature, I'm trying to channel the classy dame that is Carla Bruni. Well, not the pose-naked-and-show-the-world side of her, but the one with what people say is a Parisian's natural flair for flinging on some "simple old thing" and still looking tres chic.

Aside from the megabucks brands the French First Lady wears, it also takes a good sense of style to pass as a successful first lady, something I'm not convinced Michelle Obama has much of. The US First Lady is more hit-or-miss, plus look at the way she's sitting, at an official function, at that! Even I know that ladies and princesses don't cross their legs while sitting in public. (This is something I'm trying to channel too, but urggh it's so hard not to fidget.)

I have to get a fashion consultant! Anyone up for the job? Shopping is easy, but creating a style that looks good while also being suitable for your figure is very hard.
Also, in Paulo Coelho's book of short stories, his discourse on elegance elevates it beyond a mere affectation to something that enriches the soul. I agree, but we don't happen to come across examples of elegance too easily. (Although, there are some women in my office who are extremely well-put-together on an everyday basis and whom I try to surreptitiously eye.)
When I was in London, I tried to keep a lookout for those fabled fashionable London girls, but it was so cold that everyone was wearing huge coats. However, I did fall in love with this one girl's bright red trench coat in Edinburgh. Can I get away with wearing a trench in Kuala Lumpur, I wonder?
