Global superstar Rita has teamed up with the international fast fashion brand to launch its own multi-season collaboration.

After a week of speculation, fueled by the blackout of Primark’s windows across the shopping area, the retail chain announced Rita Ora x Primark: a versatile new clothing line that has been in the works for almost two years.

The collection, which launches on Tuesday, September 19, allows Primark customers to buy the I Will Never Let You Down hitmaker’s famous style for less.

All pieces are designed to become a wardrobe staple that you can love, wear and share season after season – a theme that runs throughout the collaboration.

Commenting on the collaboration, Rita said: ‘All my life I’ve always wanted to look stylish, and when I was younger I couldn’t have done that without Primark.

‘I could always stretch my budget with so many great items from Primark. To be honest, that’s when I really learned to get creative and play with fashion.

‘Creating this collection with Primark was very nostalgic for me, and I can’t wait for the world to see it!’

Speaking about Rita’s arrival, Jermaine Lapwood, Director of Future Trends and Innovation at Primark, said: ‘In a collaborative world, it’s more important than ever that brand partnerships are rooted in true authenticity and connection.

‘We know Rita has been a fan of Primark for a long time, but it wasn’t until we met her almost two years ago and started chatting that we realized just how much love she had for the brand.

‘The instant chemistry between the two parties was undeniable, and today, after months of collaboration, I’m so proud to unveil Rita Ora x Primark.

‘By bringing together the best of Primark and Rita, I hope the collection will empower customers to express their true selves and channel their inner Ora.’
