Perhaps Burberry's most significant contribution to fashion was the Tielocken coat, patented in 1912. This design, featuring a single strap and buckle fastening, was the direct precursor to the iconic trench coat. With the outbreak of World War I, the coat was adapted for British military officers. Features like the D-ring (for attaching grenades), gun flap, and storm shield were all added for practical combat purposes, yet they endure today as hallmarks of classic style. The trench coat’s transition from the battlefield to the wardrobes of style icons like Audrey Hepburn and Humphrey Bogart solidified its status as a timeless fashion staple.

The distinctive Burberry check—a camel, black, white, and red plaid pattern—was introduced in the 1920s as a lining for the trench coats. For decades, it remained a subtle signature. However, from the late 20th century onwards, it became a bold symbol of the brand, adorning everything from scarves and handbags to umbrellas. While its popularity led to issues with counterfeiting, the check remains a powerful and instantly recognizable symbol of Burberry's identity.

Like any long-standing house, Burberry has navigated the challenges of staying relevant. The early 2000s marked a significant turnaround under the leadership of CEO Angela Ahrendts and Chief Creative Officer Christopher Bailey. They masterfully blended the brand's rich archives with a modern, digital-first approach, making Burberry a pioneer in social media and live-streamed fashion shows. This regeneration successfully attracted a new, younger generation of consumers while respecting the company's storied past.
