It could be a scene straight out the children's book Where's Waldo? But you certainly wouldn't have much trouble finding him among this lot.
Thousands of people took to the streets in outfits identical to the children's book character in an attempt to break a Guiness World Record.
The event was arranged by organisers of the Street Performance World Championships who think up weird and wonderful ways to break records.
The character Where's Wally was created by British illustrator Martin Handford and the first book was published in 1987.
The book consists of dozens of people in a certain situation and readers and tasked with trying to find Wally among the crowds.
He is more commonly known as Where's Waldo in America and Canada as well as a number of other names around the world.
Other characters were added to the franchise, including an arch enemy Odlaw, Waldo's dog Woof and his female friend Wenda.
The campaign has obviously been successful because 3,657 people showed up at Merrion Square, Dublin, yesterday wearing striped white and red bobble hat with matching shirts and dark-rimmed glasses usually worn by Where's Waldo?.
