Having not been to Paris in a couple of years, it now seems a bit sacrilegious, to not visit such an inspiring place all the time! Beautiful buildings everywhere, and great design. Getting shown around by a local designer does help too, but I think it's impossible to go to Paris and not be inspired.
We checked out the concept shops on Avenue Montagne. Gucci, Chloe, Celine ... and our top pick, Givenchy. The mix of the old plaster work exposed on the ceiling, contrasting with felt and brass, with beautiful lighting and marble shelves, it was a real treat. Not allowed to take pics, but google images has a good selection.
