Ralph Lauren, who turns 70 next month, unveiled a fantasy farm-girl look based on all-American blue denim workwear, accessorised with sparkling dainty shoes. Models walked down the catwalk to the sounds of Woody Guthrie and Bob Dylan wearing stone-washed ripped jeans, denim overalls and flowery, country-style dresses. Blue remained the dominant colour on the runway when the workwear gave way to eveningwear, with cornflower-blue silk gowns.
