Have we got enough brands or collection that are into the nonchalance category?
2nd tier includes See by Chloé, Marc by Marc Jacobs, Isabel Marant, Paul & Joe, when highstreet are also in the game: le Redoute, Comptoir des Cotonniers ... the list just goes on and on, and of cos among all, we can't miss one of the most original nonchalance brand - A.P.C.
IMO, A.P.C. collection has been doing quite well in the last couple of season, they just launched its annual 'Madra by Jessica Ogden' collection. 15 & 8 looks for women and men respectively, all look rather tempting for casualwear, prix's been marked cheaper than the main line, check them when they arrive to your shop nearby.
