Show director Anna Mackay said about three-quarters of the entries required had been received for October's show, with another five groups still to decide.
Ms Mackay said a trust was being set up to ensure the event's future.
Above is one of the 22 entries in the last show, in 2014.
The winged outfit, made by the Albert Town creative group, was modelled by Lesley Johnston.
The three 2014 shows, plus a children's matinee, sold out.
