Northmead resident Katherine Woolnough will wear a school dress every day this October so a girl in Africa can wear one too.
The university graduate is an ambassador for the charity One Girl, whose 'Do it in a dress' fund-raising campaign helps provide primary and high school scholarships to vulnerable girls in Sierra Leone's urban and rural communities.
"We were on a holiday over the long weekend to Daydream Island and me and my boyfriend were swimming around the pool in a dress," she said.
"We got some pretty weird looks from the holiday goers, but the staff were really supportive. It [the dress] has been a good ice-breaker.
"The best way to help girls fight poverty is through education, hence the school dress.
"When you educate a girl it gives her the tools she needs to help bring herself up out of poverty, and more credibility in her social circle. It basically gives her a voice so she can be heard, plus literacy and numeracy skills to help her get a job."
Miss Woolnough said it cost $300 to educate a girl in Sierra Leone for one year. This included books, stationery, shoes, uniform and school fees.
She has done everything in a dress from trapeze, groceries and fun runs to preparation for her graduation at the University of Sydney, where she majored in gender studies.
Miss Woolnough will take part in The Hills Council's Paws in the Park walk, wearing the dress, with friends on October 20, and has organised a scavenger hunt on October 26.
Participants are asked to find locations through clues, then photograph themselves in a school dress at the different places around Sydney.
