The British are here — and they didn’t come quietly. Burberry, the London-based brand best known for its iconic trenches and signature plaid, celebrated the opening of its five-story flagship (633 N. Michigan) on Nov. 29 with a massive bash. Hundreds of the city’s most stylish bloggers and trendsetters attended, many of whom were featured in the fashion house’s “Art of the Trench” campaign. The evening started with a bang as glitter and confetti showered from the roof while the song “London Calling” by the Clash boomed throughout the store, followed by a performance by Carl Barât of English rock band The Libertines. The flagship, which has been two years in the making, marks the brand’s second-largest U.S. location and features a plaid glass façade specially created for the city by Burberry Chief Creative Officer Christopher Bailey. “People here truly enjoy style,” Bailey said. Judging by the night’s turnout, he’s right.
