Hours before the show, Kourtney took to her Instagram to tackle the backlash from the sustainability ambassador title — due to the fact that Boohoo is fast fashion and often ends up in the landfill.

Her collaboration with the company includes social content in addition to the two collections.

Kourtney wrote on her Instagram on Tuesday: “I went back and forth about this collection @boohoo because the first thing I think of when I hear the words ‘fast fashion’ is that it’s bad for our planet.”

She continued, noting that she expected the “backlash” “because the two just don’t go hand in hand,” but hopes the collaboration will eventually raise awareness about the “impact of fast fashion on our planet.”

Adding: “I thought about how impactful it would be to force Boohoo to make some initial changes and then hold them accountable for bigger changes. It certainly makes some noise and that’s exactly what I was hoping for.’

“I certainly don’t have all the answers, but for someone who has done a quick fashion line in the past, who didn’t get any backlash for not drawing attention to trying to make better changes, I’m proud to have it.” done with intention and purpose.’

‘I’ll talk about their changes, how we’ve made this line more sustainable, and what I learned was what consumers can do to help… all still!!’
