Victoria Beckham's partnership with Mango illustrates the significant progress the designer has made

In her twenties, Victoria Beckham, known then as a Spice Girl, famously expressed her ambition to become "as famous as Persil automatic." Now, entering her sixth decade, the former pop star turned designer has surpassed that goal.

Her inaugural designer collection for the high street chain Mango was launched globally online and in select stores on Tuesday. A queue had formed outside Mango's Oxford Street store in London by 8 am, with eager shoppers seeking tailored pieces, evening wear, and jewelry from her collection.

In an interview with WWD, Beckham explained her decision to collaborate with Mango as a means to reach a broader audience while maintaining her brand's aesthetic and identity. The shoppers at the Oxford Street store were predominantly millennials who grew up watching Beckham in the 90s. While many couldn't afford items from her own label, they were enthusiastic about purchasing pieces from the Mango collaboration, priced at £180.

Deborah Ogden, a personal branding expert, views this collaboration as part of a broader strategy to expand Beckham's audience and allow more people to engage with her brand. While the Mango collaboration represents an entry-level opportunity, it lays the groundwork for potential future engagements, such as makeup and expansion of her fashion brand.

Beckham's collaboration with Mango marks the culmination of a series of luxury designer partnerships unveiled by fast fashion retailers this month. Despite Mango's choice of a well-known name and a design aesthetic aligned with what shoppers associate with Beckham, the strategy has been successful. By noon, Mango had sold out of the jewelry, prompting shoppers to join waiting lists for items such as a £170 black slip dress.

This collaboration not only benefits Mango but also solidifies Beckham's status as a designer with broad appeal and as a standalone brand. While her husband, David, played a significant role in kickstarting "Brand Beckham," it's Victoria who has earned recognition as fashion's hardest worker, according to The Guardian.

Throughout her career, Beckham has evolved from her Posh Spice persona to establish herself as a serious fashion designer. This transition has paid dividends, with her brand turning a profit for the first time last year.

A Netflix series released last October further boosted Brand Beckham's visibility, documenting David's football career and garnering millions of viewers. Memorable moments from the series quickly became viral sensations, which the brand capitalized on by releasing merchandise like "David's Wife" and "My Dad Had a Rolls-Royce" T-shirts.

As Beckham enters her fifties, she shows no signs of slowing down. With her entrepreneurial spirit and continuous expansion into eyewear, handbags, makeup, and fragrance, many believe she's only just scratching the surface of her potential.
