If you run into Andrea Smith any time this month, you might notice something very familiar about her. Or more, specifically what she’s wearing.

The fashion blogger is breaking the cardinal (and rather ridiculous) fashion rule of wearing the same outfit twice, and for a very good cause. In fact, she’ll be wearing the same navy dress not twice, not even 10 times but 31 times, as part of Frocktober, an initiative to raise money and awareness of ovarian cancer.

Last year, Smith took on the challenge of wearing 31 dresses over 31 days but took a different approach this time.

“People were supportive, but there were a few raised eyebrows over owning and wearing 31 dresses! This year I wanted to take on a bigger challenge and try a more minimalistic approach,” she tellsMamamia.

“Those who know me well would likely describe me as a retail enthusiast (read: shopaholic) so sticking to just one thing all month is a bit different to my normal approach to daily style.”

The dress in question is the ‘Amelia’ dress by Aussie designer Leina Broughton, who developed the versatile dress especially after Smith pitched them the one dress, 31 days challenge.

"It's the ultimate versatile frock; it's reversible, machine wash, no iron, endlessly comfortable plus has the added bonus of being designed and made in Australia," she says.

The team gifted Smith the dress to wear and also donated $500 to the Frocktober campaign.

Smith says the secret to making the dress feel new everyday is simple - accessories.

"I’m mixing up all of my accessories – shoes, belts, jewellery, bags, hats, jackets, layering, hair and makeup. Having a navy base colour has been fantastic – it goes with nearly everything," she says.(See her looks so far. Post continues after gallery.)
