It is a way to commit serious fashion crimes and have a whole lot of fun at work, at school or in your social group.
Rotorua Museum events and engagement co-ordinator Tori Williams says there will be a range of art supplies available for people to create their own loud shirt.
However, people will need to bring along a t-shirt to decorate.
She says the gold coin entry for the event will be donated to the Loud Shirt Day charity, which helps support deaf and hearing-impaired children in New Zealand.
"This is the first time Rotorua Museum has been involved with this wonderful charity. It also provided an opportunity to work alongside the creative team at The Children's Art House.
"It will be a fun family event to raise awareness and funds for a good cause."
Money raised from Loud Shirt Day goes to The Hearing House and the Southern Cochlear Implant Programme.
The aim is for deaf children to focus on their abilities not their disability; both charities want deaf kids to be able to maximise their potential - so your donation helps deaf and hearing-impaired kids have a better future.
