NEW YORK (AFP): In his New York showroom, four books on the table sum up the passions of Tommy Hilfiger: fashion, American pop culture, rock and Grace Kelly. ‘I grew up learning to love the best parts of America,’ said the 63-year-old designer, the king of preppy chic and relaxed Americana. ‘I put them in my collection.’ This year his eponymous brand celebrates 30 years in business: 1,400 shops in 90 countries on five continents, global retail sales of $6.4 billion in 2013, collections for men, women and children, accessories and fragrance.
