Quiproquo by Grès is one of the sharpest, greenest floral chypres I've ever had the pleasure of smelling.
It opens like Estee Lauder Aliage (1972), with what smells like a huge dose of galbanum and peach; blooms like Diorella (1971), with fresh florals, aromatic herbs, and a bit of funk; and it dries down a bit like Grès’s Cabochard (1959), with a subtle leather accord that pulls the fragrance together like a tough leather belt around a diaphanous summer dress.
The writer for perfume blog Black Narcissus calls Quiproquo "Cabochard’s little sister," and a Fragrantica commenter agrees, derisively describing Quiquopro as “1/4 Cabochard, 1/4 lemon cologne.” It’s true, lemon slices through Quiproquo like a golden ray of sunshine, but once its puckering intensity dies down, the floralcy and woodys/chypre/leather base take over. Raiders of the Lost Scent blogger Andre says of Quiproquo, "Sweet, gentle, almost ethereal, it seems to ask permission before appearing."
Huff this stuff long enough, and you can sniff out the isobutyl quinoline that made Bandit and Cabochard great, giving Quiproquo a dry mossy leather finish so characteristic of 70s perfumes of either persuasion.
