About Us

In 2010 – fresh back from spending a year working for an emerging label in Sydney – Bill and Mar founder Rosie Bonnar was back in London and noticed a gap in the market for fashion forward urban designs without the designer price tag. Inspired by the huge cultural fusion and energy of London Bill+Mar grew into an eclectic mix of signature prints and ready to wear collections, designed to make you feel confident, comfortable and sexy. (Bill+Mar is named after Rosie’s Grandparents: Bill and Marion. Their love story has lasted 60 years).

Bill and Mar is all about expressing creativity, standing out from the crowd and creating your own unique look. New prints designed in house for each collection are influenced by the iconic street style of London, and is loved by celebrities and bloggers alike including Ellie Goulding, Rita Ora, Cara Delevingne and Charlie Barker.

Bill and Mar isn’t just influenced by London – it’s made in London too. With our fabric sourced and printed in the UK, our full collection is produced in our factories in London.
