$9000 haul hidden inside Australian mum's home

Belinda Robinson estimates she has spent at least $9000 on her daughter Jessica's dance outfits over the years, most of which are currently crammed into a room in her home.

"Since Jess started dancing, each year we have spent about $700-$800 on group costumes and $1500 on solos," Belinda tells 9Honey.

Jessica has been dancing since she was three. With each year brought more sequins and feathers and and dance outfits she would wear a handful of times and then never use again.

She's grown out of many of them by now, leaving Belinda, 48, with a dilemma.

Should she keep them, throw them all out or perhaps sell them.

It's a dilemma many Australian families whose children participate in activities outside of school face.

Belinda collected her own assortment of outfits from her ice-skating days when she was younger and never knew what to do with them.

The Sydney mum decided to try to sell some and turned to Facebook Marketplace but it wasn't a simple process.

"Half the time you can't even find your own post," she says. "And there's hundreds of different groups."

After chatting with some fellow dance mums in a similar predicament, Belinda decided to launch her own website dedicated to selling dance outfits called Redance

"We've had so much interest and everyone's so excited about it, it's just getting that momentum," she says.

It's a perfect solution and one that will serve Belinda and her daughter Jessica as Jessica continues to perform, something she loves.

"I actually really like the community that it has," she says, adding that her daughter has formed friendships outside of her school group that will last a lifetime.

Some early challenges for the business include collecting the outfits for sale and assisting sellers in uploading images onto the site, but she has plenty of ideas including setting up drop-off points at local dance shops and offering incentives for those who choose to sell them from home.

Oftentimes families are happy to donate their dance outfits for sale, with Belinda keen to donate the proceeds to dance companies that host disadvantaged and disabled children.

"Redance is about reusing, recycling and reselling," Belinda explains, adding that the young dancers themselves can get involved in reselling their outfits on the website.

"Children are so clever at just uploading and working things out," she says. "I feel like that's actually going to work better than the parents doing it."
