The parade is part of the 'Arts is Alive' celebration at the George Arts Theatre.
The stalls will open at 10:00 and the parade starts at 11:00.
The parade has a dual purpose and is being held to market the show, When You Wish Upon a Star, which will run from 24 June to 3 July at the George Arts Theatre.
Manager Heather Stead says the parade also celebrates the theatre's new look and fun, fabulous vibe. "The George Society of Arts is proud to announce the sequel to the sold out 2014 show, When you wish upon a star. The kids went wild about this show in 2014, and the sequel will be just as exciting."
She says the festivities will start with a fantastic parade staged by the theatre wardrobe on Saturday 18 June, and end at the theatre where there will be a festival market with live entertainment, stalls and fun for all.
Heather issued an invitation to all Georgians to go all out and dress up. "Join Belle, Cinderella, Snow White, Tiana, Rapunzel, Ariel and Aurora, better known as Sleeping Beauty, as they try to get back to their happy endings!
They get thwarted and misled by the devious Mother Gothel, Ursula, Wicked Queen and Cruella de Ville - to name but a few. But they get help from the fairies and some superheros and learn that true strength comes from inside."
