Naomi’s collaboration with PLT was announced last month, with some expressing their distaste over promoting fast fashion.
Yet hitting back at the critics, Naomi revealed it was important for her to team up with the leading fashion brand in order to help the designers she’d worked with.
She told Women’s Wear Daily: ‘I’m looking at myself as a changemaker. As a changemaker, I thought this was something that was a good thing to do.
‘I know that it’s fast fashion, and that people have their criticism. I’m not denying them. But as a changemaker, I felt this was a great way to effect change in the industry in getting my emerging designers recognized and seeing them on a global platform.’
Naomi – who has spoken openly about her issues with racism in the fashion world – also discussed her thoughts on ‘diversity’ in the industry today.

She explained: ‘I’m so over the word. This is my point – I feel like so many people just use that word to tick a box, to make sure that they’re not called out or anything like that.
‘I don’t use that word. For me, it’s not about using the word or ticking a box — it’s about doing the action, the pure action. It’s giving a part of your platform and sharing it with someone, who is talented.’
The exclusive line designed by the British fashion icon will launch next month at New York Fashion Week.
It comes after Naomi teased that she could be appearing at Victoria Secret’s star-studded Pink Carpet event to launch their ‘World Tour’ on Prime Video.
She took to Instagram on Thursday to share a glamorous snap of herself to promote the launch event and The Tour 23 which is released September 26.
Ahead of the movie will see a celebrity-filled bash gather to celebrate the success of the campaign on September 6.
On Wednesday, Victoria Secret revealed some former and recent model’s who will be attending the star-studded event and also teased to ‘stay tuned’ to some other familiar faces which could make an appearance.
The underwear brand has launched the campaign to bring back models from the lingerie brand’s once-iconic ‘Angels’ list alongside some newer faces.

The brand, which launched a new The Icon Victoria’s Secret collection in August, is so close to releasing the new film-style fashion show next month.
The campaign is part of the company’s major rebrand, after it was criticised for promoting unrealistic body image with its non-inclusive culture and accused of failing to protect its models against sexual misconduct.
Julia Fox, Adriana Lima are two stars that are not yet confirmed whether they are making an appearance at the event, VS revealed on Instagram.
VS hinted that Lila Moss, Gigi Hadid, Hailey Bieber and Naomi Campbell will all be making a debut at the biggest fashion event next week, which will see all former VS angels and recent angels come together in one building.
