The 21-year-old, who recently launched an online shop, is searching for his next OZ boardies design.
There are two categories catering for youngsters up to 16 and A3 designs can be submitted at the festival.
Winners will receive $300 of OZ gear and be part of Mr Myers’ design team.
Mr Myers designed the centenary shorts for North Cottesloe Primary School and North Cottesloe Surf Life Saving Club’s shorts ” both organisations will be involved in the November 9 street festival that will run from 9am to 5pm.
He said the festival would be great for brand awareness because Cottesloe and its surrounds were his target audience.
Hullaballoo, which is sponsored by the Western Suburbs Weekly, is in its fourth year and will include food, wine and local produce displays, as well as musical performances and stalls hosted by community groups and businesses in Napoleon and Station streets.
There will be face painting, balloon twisting, a petting zoo and performances by the Spare Parts Puppet Theatre.
ProCott president Phillip Angers said that they hoped to attract more than 5000 people to the streets of Cottesloe.
