What can I say?! Audrey Hepburn wore them in Breakfast at Tiffanys, Tom Cruise in Risky Business, Daniel Johns (at the Arias?) - not to mention Marilyn Monroe, John Lennon, Bob Dylan and J F Kennedy. Now they've made yet another comeback on the likes of Rachel Bilson, Chloe Sevigny and Mary-Kate Olsen. Iconic! I couldn't help myself, I bought a pair (tortoise shell of course) on Saturday. Sexy little things.
