DIRTGIRL invites everyone to rock up with their funkiest reusable bag and strut the green carpet with her for a chance to win prizes on World Environmental Day on Tuesday.

Dirtgirl will be appearing live at Grafton Shoppingworld for the launch of her world-first 21 Day Plastic Free Detox.

From July 1, free plastic bags will be phased out of major retail stores, and Dirtgirl's 21-day plastic bag detox is created to assist the community in transitioning to a life without plastic bags.

You can sign up for free from June 5 at Shoppingworld and join in Dirtgirl's bag parade and workshops.

After signing up, a funky email will arrive each day in your inbox from Dirtgirl to help you reduce plastic usage this June - with tips, ideas, reminders and a special coupon to collect your free reusable shopping bags. There will also be an opportunity on the day to make your own reusable bag and your own beeswax lunch wrapper.

"We are doing the detox because we are on the edge and stepping into a plastic-free Shoppingworld,” Dirtgirl said.

"Getting used to re-using and breaking up with single-use plastic bags and bring bags with us every time we shop.”

Workshops and parades at 11am-1pm and 3-5pm at Grafton Shoppingworld on June 5
