city guide on my mind

‘The Fashion Insiders’ Guides are carefully curated compendiums of the current hotspots, classic haunts, and hidden gems of the world’s greatest fashion destinations. A former Parisian living in New York, French Vogue correspondent Carole Sabas was often approached by friends and colleagues on their way to Paris for Fashion Week, looking for the best place for a quick facial, early morning yoga, or to meet a friend for a drink. So many people asked, in fact, that she produced a small guide filled with advice, which she gave out for free. Requests for more information and other cities came pouring in.’
