By Li-mei Hoang LONDON (Reuters) – Britain’s established designers took to the stage on the fourth day of London Fashion Week on Monday to showcase their latest collections featuring tulle dresses, sequined tops and sheer floor length gowns. Burberry, which is celebrating its 100th anniversary of its iconic trench coat, sent models down the runway in a riot of bright colors and prints inspired by the British countryside, book covers and all things “contradictory”. “We had been looking at this idea of the ‘birds and the bees’ and feeling very free,” Burberry’s Chief Creative and Chief Executive Officer Christopher Bailey told Reuters. The British label’s signature trench coat also featured bold abstract prints and were emblazoned with slogans such as “insects” and “flower”.
