BARTON PERREIRA Crescendo Square-frame Tortoiseshell Acetate Sunglasses

Barton Perreira likens the bold, layered construction of these sunglasses to a 'Crescendo'. Crafted in Japan from tortoiseshell acetate, they're fitted with smoky lenses that extend beyond the square frames to exaggerate the proportions. Each pair takes weeks to meticulously finish by hand.
