Existing and new customers are encouraged to visit their local Vinnies Shop to explore unique treasures, choose something they love, wear it and share it on social media by tagging #DressedbyVinnies.

Cassandra Nicholson store manager said the Wagga shop has such a wide variety, whether you are looking for formal wear or costumes for a themed-party.

"We have retro hunt items which people are on the hunt for constantly," she said.

"I think people are surprised by the value and the quality of the items.

"I think our society is more aware of upcycling, recycling and we seem to be able to do all of those things here."

Ms Nicholson said people should consider checking out the store and becoming a volunteer.

Vinnies NSW CEO, Jack de Groot, said the bonus is helping support the community and contributing to recycling and waste reduction efforts by shopping sustainably.

"Research indicates that Australians buy an average of 27 kilograms of new textiles each year, including clothing and sheets, and throw away around 23 kilograms of the same," he said.

"By shopping at Vinnies, you can reduce your carbon footprint and at the same time help make someone's life a bit easier.

"Last financial year, 29 per cent of the total revenue generated by Vinnies in NSW came from Vinnies Shops, enabling the organisation to support tens of thousands of people experiencing homelessness, domestic violence, disability, poverty and other forms of disadvantage."
