Thousands of people took to the streets of Londonderry on Sunday afternoon in an attempt to break a world record for the most people wearing Christmas jumpers in one location.
The festive music blared out in the Walled City as the Christmas spirit took hold of those gathered.
The number they needed to beat was 3,743, with the previous record having been set in Kansas, America.
They will find out whether the record was broken once those verifying the attempt have made their final count.
One of the city's most iconic sculptures was also decked out with Christmas jumpers.
'Hands Across the Divide' by Maurice Harron was bedecked with festive apparel on the Craigavon Bridge.
A spokeswoman for the organisers said: "It was a great turnout, very successful.
"If we get the record it will be the icing on the cake."
She said verifying whether the record has been broken could be a lengthy process because everything had to be double checked.
"We will know unofficially if we have been successful later in the week but the formal confirmation will be in the New Year."
Those with muscular dystrophy will be among those to benefit from fundraising during the event, with many paying more than the donated entry fee to take part.
