Her growing fame in the modeling world is reflected in her substantial Instagram following, which exceeds 565,000 fans who regularly engage with her content showcasing luxury brands and photo shoots.
Entrepreneurial Ambitions During the Pandemic
Beyond modeling, Donaldson has pursued her entrepreneurial dreams by launching her own clothing line, Muse Activewear. The lockdown period provided her with the chance to focus on building this business. She explained that spending extended time at home during COVID-19 initially made her feel “a little purposeless.” However, she used that time to develop her brand and redirect her career goals.
“I was spending many days and hours during lockdown feeling a little purposeless,” she said (via PEOPLE). “So, I decided to pursue my dream of starting a clothing brand.”
Prior to this venture, Donaldson briefly worked in a corporate job but left after around six months to concentrate fully on her brand.
“I’ve part-time worked in that sort of role however I’ve only ever lasted around 6 months,” she said. “This is probably part of the reason why I decided to start my own business!”
