While most of the lads arrived as T-Birds' leader Danny Zuko, Arg decided to channel his inner geek and dressed as gullible nerd Eugene Felsnic!
Arg looked slightly cooler than Eugene however, donning a leather jacket, white shirt and a black bow tie. He completed his look with thick-rimmed glasses and slicked back hair! And didn't he look pretty pleased with himself as he posed for a picture?!
Embracing the party's theme for all things 50s, Arg was later seen joining James 'Lockie' Lock on a ride and running through the fairground in Kent with his co-stars!
It was bad day for Arg on Sunday's episode of TOWIE (27 July), as he revealed that ex-girlfriend Lydia was no longer speaking to him following new allegations that he had a threesome during their relationship three years ago.
The week before, viewers saw Arg heartbroken, after Lydia explained that despite their recent reunion, she didn't want them to be in a relationship again.
On Sunday, Arg also found himself in the bad books of good friend Jessica Wright and her mum Carol, who accused him of starting a family argument at Leah Wright's recent wedding in Alicante, Spain.
Arg tweeted after the show: "It's fair to say I took a good #BeatDown and #Asswhooping on @OnlyWayIsEssex last night but it's not over until the fat Arg sings! Lol."
The final episode in the current series of The Only Way Is Essex airs on Wednesday 30th July on ITV2 at 10pm.
