Miss Sixty has never taken herself too seriously. She’s never toed the line of convention for anyone’s sake, never been afraid to smirk at the rules. She’s always dressed just as she wants, not how she’s told, always taking what should feel wrong and making it feel so damn right.
Through a collaboration with the lore-steeped ready-to-wear brand, Alexandre Arsenault and Charlotte Knowles – the creative duo behind London-based label KNWLS – reanimate and reimagine Miss Sixty’s quintessential spirit for today.

London-based label KNWLS – rebranded and renamed from Charlotte Knowles in 2021 – was founded in 2017 by Charlotte Knowles and her partner Alexandre Arsenault, who met while studying at London’s Central Saint Martins. KNWLS strives to embody an empowered yet disruptive vision of femininity – one that is simultaneously dangerous and sensual. It offers a fierce, unapologetic wardrobe that allows room for self- expression, where each piece acts as armour against the world. Having first shown on-schedule at London Fashion Week in 2018 as part of the talent incubator Fashion East, KNWLS drew attention for its slick, body-conscious separates that played with concealment and exposure. KNWLS secured spots as an LVMH Prize 2022 finalist and a BFC/ Vogue Designer Fashion Fund 2024 finalist, and is nominated for British Womenswear Designer of the Year at The Fashion Awards 2025.
