Modibodi’s myth-busting strategy redefines marketing to menstruators 

Daring Shark Week stunt demonstrates period swimwear works, driving 7% year-on-year growth

According to period underwear and swimwear brand Modibodi, 45% of menstruators (1.5 million people) fear swimming on their period, with one of the biggest barriers to trying period swimwear being the fear of sharks detecting blood.

In July 2024, Modibodi and agency Fabric (part of the TBWA\Sydney Group) created a stunt to demonstrate the efficacy of its period-proof swimwear and break down myths and fears surrounding menstruation.

During Shark Week (an annual broadcast event hosted by the Discovery Channel that focuses on sharks and their ecosystems), freediver and marine biologist Brinkley Davies swam with 5-metre tiger sharks, while on her cycle – wearing only a Modibodi swimsuit. 

A campaign film following Davies’ dive and featuring Modibodi’s swimwear launched online and on social channels in Australia and the UK. The Shark Week campaign is part of Modibodi’s Fear Not platform, which aims to shut down menstruation myths.

‘This simple act is a disruptive product demonstration, a statement of empowerment and a great articulation of the new brand platform Fear Not,’ said Keenan Motto, creative partner and co-founder of Fabric, in a statement. ‘Obviously not everyone wants to swim with sharks but it’s a testament to the quality of the product and its efficacy. Partnering with director Kyra Bartley at Finch, the centrepiece of the campaign documents the dive and captures our diver, Brinkley Davies’ fearless spirit and Modibodi’s stylish leak-proof swimwear.’

Results / According to the agency, the campaign achieved a reach of 61 million and drove a 13% increase in consideration and 7% increase in year-on-year growth.

Contagious Insight 

Strike when the time is right / Shark Week may be a US-based phenomenon, but its significance in Australia can’t be overstated. Much of the shark-based content is captured on Australian shores, with insights from Australian and New Zealand researchers and scientists, reaching a large Australian audience. Beyond being a buzzy media moment, Shark Week is about education and awareness, helping reshape perceptions of sharks and driving shark conservation efforts. Modibodi’s myth-busting educational stunt was perfectly in line with the tone of Shark Week – PR-friendly and splashy enough to stand out in the sea (pun intended) of shark content, but ultimately designed to challenge perceptions and dispel fears. As an Australian brand, Modibodi was well placed to activate around this occasion and respond to a genuine fear among menstruators in this region. 

Make them forget it’s marketing / As Modibodi’s former CMO Liana Lorenzato told Contagious in 2023, the brand needs to prove its quality and efficacy to consumers to justify its price point. ‘They need to really trust that it’s going to work,’ she said. ‘If they’re investing in something that, upfront, is typically more expensive than a disposable product, they need to know that the product is going to last.’ The Shark Week campaign is a clear response to that challenge – is there a more convincing or high-stakes product demo than having a menstruating woman swim with sharks? More importantly, the content is so engaging that you forget you’re watching an ad for Modibodi’s Anti-Leak technology. In a saturated, competitive category, Modibodi has found creative ways to cut through, such as its TikTok content series that racked up 12 million views in four weeks, and Postpartum Unfiltered, a social change project to reflect postpartum experiences.
