Cat O'Brien

Cat O’Brien is a sustainably focused, historically inspired fashion brand based in Brighton, UK. 

Since graduating from a Fashion degree in 2019, Cat has honed her eponymous label trying to focus on a ‘slower’ approach to fashion, endeavouring to create less waste and design classical yet timeless ready-to-wear garments using entirely deadstock and remnant fabrics. Operating with a made-to-order system, we ensure no waste with overproduced items, as well as being able to create bespoke sized pieces that you wouldn't be able to with items already made up. With an inherent draw to all things costume, be that Victorian era pieces, or Campy Halloween, the designs draw on a combination of close attention to period details, plus modern twists. Our initiative 'Secondhand Cat' aims to made Cat O'Brien a circular brand by giving an incentive to make as much as we can have at least a second life.

In the 4 years the brand has been running, Cat’s work has been featured in an exhibition in the Saatchi Gallery, had pieces in Wonderland, GQ, and the cover of Desnudo, as well as styled on the likes of Jordan Stevens, The Last Dinner Party, and Cassyette. Alongside the brand we aim to give back to communities as often as possible, and are proud to have donated profits to numerous charities including Gendered Intelligence, Exist Loudly and Solace Women's Aid.

Above all we aim to create pieces you'll want to invest in and keep, in the knowledge you have purchased something created in the most mindful way possible.  All pieces are designed and made in house by Cat in our Brighton studio.
