Brand spokesman Jude Law celebrated the opening of the new Home of Dunill in London's Mayfair neighborhood. “I think men lost something when they stopped wearing hats and suits,” Law told People. “A hat is also something slightly effeminate, the way you wear your hat, it’s very personal-I love the quaint traditionalism of that.” Singer Lily Allen also showed up to salute the classic menswear label.
