An Avenue Montaigne fashion boutique transforms into a hall of mirrors, cut as a dressmaker might cut cloth. In the entry of the haute couture section, a glass panel of light frames a granite sculpture.

Polished black granite floors, work surfaces, walls, and pillars in silvered smoked glass, along with frosted glass screens, create a glittering jewel case for the creations of couturier Jean-Louis Scherrer. A spiraling staircase descends into a block of granite.
