About Us

Founded by designer Rosie Bonnar in 2010, Bill†Mar was named
after her grandparents; Bill and Marian. After an inspirational
year in Sydney working for an emerging young label, Rosie
returned to London with the motivation to start up and launch her
own directional label. 
Bill†Mar does not conform to regulations and is not afraid to
deviate from mainstream trends. Its mix of fabrics, prints and
textures make it stand out from the crowd.
It is about creating a unique personal wardrobe with a focus on
silhouette – body con, cropped or mini wherever possible. The label’s
fashion forward style makes it a unique and exciting addition to the industry.
