You can call them an offshoot of the tiny sunnies that fashion It girls like Bella Hadid, Rihanna and Millie Bobby Brown popularised last year. The big deal about those was their demure size and the way to wear them (perched on the nose bridge a la bifocals). This season, brands such as Prada and Louis Vuitton serve up something more original: a style that looks like a mash-up of slender, feline-inspired frames from the ’60s, and the hyper-slick ones Trinity had on in The Matrix. What makes them truly fresh and not gimmicky: You can wear them normally and still look cool.
