(Reuters) - Hugo Boss has struck up a multi-year design partnership with Former Manchester United midfielder David Beckham, the German fashion house said on Thursday, as it seeks to boost demand for its Boss brand.

The collaboration includes collections designed and curated by David Beckham for both formal and casual menswear, the company said, with the first collection to launch in spring/summer 2025.

The German fashion house is on an expansion mission, increasing marketing spend after a brand revamp in 2022 and opening 102 new points of sale in 2023, but its shares have fallen this year as it warned of slower sales growth.

Beckham will already appear in the brand's global campaign in fall/winter this year.

"David Beckham is a true global icon in both sports and fashion. With his distinctive entrepreneurial spirit and authentic passion for fashion, he perfectly embodies the values of our BOSS brand," CEO Daniel Grieder said in a statement.
