For the past three decades, it's safe to say Victoria's Secret has dominated the lingerie space. And while many brands have launched and evolved over the last 30-or-so years, VS is one that has, for the most part, remained the same. With the brand's annual "fashion show" — which is essentially a glittery striptease featuring predominantly tall, thin models in diamond-encrusted bras none of us can afford — happening next month, the brand's diversity problem is coming to light.

The Victoria's Secret Fashion Show is a major network TV event and women (and men) across the country tune in, but former viewers aren't so sure it's the best thing for impressionable young girls to be watching.

In fact, Robyn Lawley, the first plus-size model to be featured on the cover of Sports Illustrated back in 2015, is calling for a total boycott of the event.

She's primarily concerned with the brand's lack of body diversity in the show — and its refusal to change. Despite the widespread acceptance of different body types across the fashion industry, Victoria's Secret always sticks to the same outdated formula. Sure, the brand has finally incorporated a wider range of ethnicities, but the models all have the same body type: tall and thin, with very few curves.

She took to Instagram to voice her concerns, saying, "Victoria’s Secret has dominated the space for almost 30 years by telling women there is only one kind of body beautiful. It’s time Victoria’s Secret recognized the buying power and influence of women of ALL ages, shapes, sizes, and ethnicities. The female gaze is powerful, and together, we can celebrate the beauty of our diversity. It’s about time Victoria’s Secret celebrated the customers that fuel its bottom line."

Victoria Secret have dominated the space for almost 30 years by telling women there is only one kind of body beautiful. - you can read more in the link of my bio why it’s so important to encourage diversity for our future daughters sake. Until Victoria’s Secret commits to representing ALL women on stage, I am calling for a complete boycott of this year’s Victoria’s Secret Fashion Show. It’s time Victoria’s Secret recognized the buying power and influence of women of ALL ages, shapes, sizes, and ethnicities. The female gaze is powerful, and together, we can celebrate the beauty of our diversity. It’s about time Victoria’s Secret celebrated the customers that fuel its bottom line.

Thus, she teamed up with lingerie company ThirdLove to form a petition, asking people to boycott the fashion show until the brand "commits to representing all women onstage."

As of now, over 8,000 people have signed the petition. So it's pretty obvious people are fed up with the brand's singular idea of beauty.

Meanwhile, Bella Hadid confirmed she'll be walking in this year's show with a series of lingerie-clad photos in which she looks even thinner than usual. Some of her fans are even concerned that she looks unhealthy.

"Shame on @victoriassecret for encouraging and promoting this totally unrealistic image. We must put an end to the concept of looks = value," one commenter wrote.

Hadid's images only increased the backlash against the brand. And looking through the list of models confirmed for the 2018 fashion show is just further proof the brand only hires thin women.

Kendall Jenner, Winnie Harlow, Gigi Hadid, Barbara Palvin, and Yasmin Wijnaldum are among some of the others. So far, no curve models were cast to walk in the show.

Lawley's issues with Victoria's Secret reflect a wider dissatisfaction with the brand's marketing over the past few years. It turns out millennials, as a whole, don't seem to buy into the brand's narrow idea of beauty as much as earlier generations. In fact, its sales and stock prices have been declining.

Instead, women are turning to brands like Aerie and ThirdLove that embrace inclusivity and un-retouched bodies.

If Victoria's Secret keeps refusing to change with the times, they risk more than losing the fashion show audience. They risk losing customers altogether.

The fashion industry is changing and finally realizing there's more than one standard of beauty. It's time Victoria's Secret opened its eyes.

As she so gracefully put it: "Let’s start reteaching everyone that there is more than just one kind of beauty or one kind of sexy."
