By Isla Binnie MILAN (Reuters) – Models stalked around a fiery lake at Roberto Cavalli and were swathed in luxurious lambskin at Bottega Veneta in Milan on Saturday for the city’s biannual women’s fashion week. A pattern of scarlet flames licked around the hem of a black evening gown and beaded flapper dresses reflected blue spotlights and the glow of real fire at Cavalli’s show. Bottega Veneta chose powdery pink, grey and beige for shearling coats, linear crepe dresses and pleated skirts, adding the occasional flash of purple, emerald green and red. Italy’s national chamber of fashion (CNMI) expects the industry to make 62.5 billion euros ($85.91 billion) in revenue in 2014, returning to sales growth after two years in decline.
