In a season that’s been anything but conventional, Ricky and Haydn from The Block have once again shocked fans by turning up to the auction day in daring attire.

On Saturday, the cheeky duo were pictured sporting nothing but tiny budgie smugglers, flamboyant hats, and eye-catching accessories as they arrived on set.

The Melbourne best friends, who had a tumultuous final week after firing their builder due to substandard waterproofing, took their fashion statement to a whole new level.

In a cheeky twist, the best mates donned colourful swim briefs that left little to the imagination.

Haydn, dressed in vibrant neon-patterned briefs, teamed his look with neon orange socks, white sneakers, and a bold, rainbow-tinted visor.

Ricky, equally unabashed, wore red lobster-themed briefs, pairing his outfit with a playful multicoloured cap and white socks and shoes.

In another appearance later in the day, the duo turned up in more refined yet quirky suits.

Haydn opted for a crisp white suit paired with a purple shirt and coordinating bow tie, accessorised with a pocket square in a fun, contrasting colour.

Ricky and Haydn’s frustration boiled over last week after foreman Dan pointed out that their property’s waterproofing did not meet building standards, necessitating a costly redo.

Their clash with builder Miller, whom they eventually fired, was one of the season’s most intense scenes, with the friends candidly expressing their dismay at the project’s setbacks.

Despite the bumps along the way, Ricky and Haydn’s choice to embrace humour on auction day resonated with fans, who were quick to applaud the duo for their lighthearted antics amidst the tense finale.

With all five properties from this season’s Block, located in Cowes on Phillip Island, set to go under the hammer with a price guide of $1.7 to $1.85 million, the auction promises to be an exciting end to what has been one of the show’s most unpredictable seasons.
