Beautiful!

Just in case no one's already posted this.
My wife's bought some things from there. The woolen trousers for women a few seasons back, in a Kate Hepburn style, are beautiful. And timeless. Didn't really see anything on my last visit (during the Winter season) that I wanted. Perhaps it shows my poverty of the imagination, you'll say.
Their things don't fit in with my aesthetic but they are exquisite. If you have the inclination and the scratch, then indulge yourself.
I've always found more to buy in the nearby Bon Marche: http://www.lebonmarche.fr/bonmarche.html#home
Young girls leave flowers there at the foot of the wall of socks for Horace.
Yeah, a great store. I really should try to spend more time in the ladies section in the front though. No one does stockings (or if French women are to be believed on French men, stalkings), like the French.
