Burberry unveiled its latest B-Series at noon GMT today (January 17, 2019), exclusively through Burberry’s Instagram, LINE and Kakao platforms. It will remain available for 24 hours.

The limited-edition unisex pieces, a red Thomas Burberry Monogram polo shirt and sweatshirt, drew inspiration from the debut runway collection of the fashion house’s Chief Creative Officer Riccardo Tisci. The latest B Series release features the TB Monogram which was designed in collaboration with British graphic designer and art director, Peter Saville.

The new monogram, which launched in August 2018, celebrates the heritage of the fashion house in a return to the spirit of its founder, whose initials are referenced in the design.

Burberry’s B-Series forms part of a series of monthly product drops designed by Riccardo Tisci. Ever since he assumed the role of the Chief Creative Officer at Burberry, he has been switching up the brand’s release strategy. As part of the fashion house’s new and aggressive marketing plan, Burberry releases its B-series on the 17th of every month.

The first product of the series, a limited-edition run released on October 17, consisted of a unisex white T-shirt and jersey sweatshirt featuring Burberry’s new ‘TB’ monogram in red, a nod to the brand’s founder Thomas Burberry.

Why the number 17? Apparently, it is Tisci’s lucky number. In addition to it being a part of the designer’s Instagram handle (@riccardotisci17), he has made numerous references to the number throughout his career. Most recently was for his Burberry debut itself, which occurred on September 17th last year at 17:00 hrs.

The next B Series will be released on 17 February 2019.
