Youssef Marquis, a longtime communications executive for LVMH’s Givenchy and Louis Vuitton labels, is set to open a new Paris-based agency with support from the French luxury conglomerate.

The namesake agency Marquis has partnered with LVMH to consult for brands across the group, as well as taking on external clients, working on celebrity marketing, image and strategic communications.

Working closely with stylists, agents and talent, Marquis has played a key role connecting LVMH with pop singers, influencers and Hollywood stars as celebrity marketing gained importance in the fashion industry.

During 12 years at Givenchy alongside designers Riccardo Tisci and then Clare Waight Keller, Marquis helped the couture house to renew its cultural relevance by dressing stars like Beyoncé, Madonna and Kim Kardashian (becoming the first European luxury brand to embrace the American reality-TV star). The executive remains close with both Tisci and Kardashian.

In 2018, Marquis helped Givenchy score one of the biggest celebrity placements in recent memory: designing the dress for actress Meghan Markle’s wedding to Prince Harry.

As fashion communications director at Louis Vuitton since last year, Marquis has assisted the brand in cutting deals with a fresh crop of A-list ambassadors including Cate Blanchett for jewellery and Bradley Cooper for watches. He also helped the brand to secure talent for a recent campaign featuring rival football superstars Lionel Messi and Cristiano Ronaldo, timed to coincide with the FIFA World Cup.
