Goddard grew up in Ladbroke Grove and trained at Central Saint Martins with the intention of working for a fashion house, not thinking she could have her own brand. Her eponymous brand came "accidentally" in 2015 when she started to struggle at the school and threw a fashion party for friends with designs that soon became noticed and took orders.
In 2016, Goddard was awarded the Emerging Talent award at The Fashion Awards and was shortlisted for the LVMH Prize 2017. In May 2018, Goddard won the BFC/Vogue Designer Fashion Fund, winning the BFC Fashion Trust grant in May 2019.
Her style involves directly manipulating materials, not just creating designs, for which she prefers to use cheaper fabrics. Vogue credits her style as one of the progenitors of feminism in fashion, noting that while "At first glance, her clothes may look frou-frou, [...] she likes them to have a subversive streak".
The success of her label in the United States has been attributed to singer Rihanna wearing her designs on red carpets since 2016, and celebrity muses, like model Edie Campbell, who first walked for Goddard in Spring/Summer 2018. More recently, Molly Goddard dresses featured in the BBC and BBC America television show Killing Eve on actress Jodie Comer.
