These brown Prism 'Calvi' tortoiseshell sunglasses are vital to your health and overall well-being, for in the words of Anna Dello Russo 'accessories are like vitamins to fashion – as such you should use them liberally'. Exquisitely handcrafted in Italy, the brand's 'Calvi' cat eye model features a brown tortoiseshell acetate frame and tinted Carl Zeiss lenses which provide UV protection. We'll be wearing our Prism sunglasses our Gstaad chalet terrace with a glass of vino in one hand and the snow-covered mountains stretched out before us.
