Roberto Cavalli

These teal-green velvet trousers capture Roberto Cavalli's affinity for the 1960s and 1970s. They are made in Italy to sit high on the waist and have flared legs for a suitably retro feel. Unfinished hems mean you can alter the length easily. Tuck in a floral-print blouse and finish with strappy sandals for the most authentic evening look.
