15. Turnbull & Asser
Founder: Reginald Turnbull and Ernest Asser
Year Founded: 1885
In many ways, Turnbull & Asser define the British shirt. Their flagship store, on London's Jermyn Street, is the anchor for a strip of great English shirtmakers, and has been since the very start of the 20th century. While T&A makes many garments besides shirts, shirts are their core business. The classic British style is a staid, often solid-colored suit, a simple tie and a bold shirt, and if you're looking for the shirt part of that equation, T&A is where you will likely head. The company offers bespoke and off-the-peg shirting, and has made shirts for Prince Charles since the Prince was a boy.
