Each of L’Eclaireur’s five shops is filled with chic de­­signer goods. But it was Azzedine Alaïa who told me about the lo­­cation near Place des Victoires. Hidden behind 17th- century doors with a discreet buzzer, the boutique carries silk organza blazers by Paul Harnden ($1,700), spectacular objets such as a ram’s-head lamp ($3,800), and the largest globe I’ve ever seen ($25,000). At 10 Rue Herold; 33-1/40-41-09-89.
