Balenciaga is credited with last year’s biggest eyewear comeback – thanks to the brand, the thin, rectangular shades that hadn’t been seen since the '90s were suddenly on every catwalk. It’s a diverge that shows no sign of slowing down, so look to the originator for your set; this slimline black acrylic pair is made in Italy from slick, high gloss acetate, then marked with the house’s iconic name at the temple.
