Marshall Thompson’s obsession with British fashion started in high school in Lancaster, Pa., where instead of tipping cows, he listened to the Clash and the Specials. “They always wore Fred Perry and Ben Sherman, and I thought it was the coolest thing ever,” he says. After graduating from American University in 2003, Thompson moved to London, where he discovered that Blighty offered more than tight collared shirts. He opened his first store two years later, in a basement along 18th street in Adams Morgan. Last fall, he followed the dollar to Georgetown and built a proper men’s boutique, complete with custom wallpaper of English street maps and bookcases that turn into dressing rooms. He sells men’s labels like Fred Perry, Ben Sherman, Merc, Boxfresh, Oliver Spencer, and Ted Baker. He sells affordable suits with that narrow English cut ($400-$800) and streetwear more appropriate for playing hooligan at a D.C. United match. Most of his extensive inventory is available online. And this spring, Thompson will reintroduce women’s lines.
