[1][2] Reinaud founded Seraphine in 2002, and the brand received worldwide attention when the Princess of Wales, then Duchess of Cambridge, was pictured wearing the designer maternity clothes through all three of her pregnancies.

[8] Reinaud developed an interest in fashion early on, as her grandparents owned a fabric company in France that supplied materials to renowned brands such as Chanel and Lanvin.

[9][10] After earning a business degree, Reinaud moved back to the United Kingdom and started her career in advertising.

While serving as the youngest account director in JWT's history, Reinaud was inspired to found her own company by several pregnant friends who requested tailored clothes during their pregnancies.
