Drayton Manor will attempt to break the world record for the largest number of people wearing onesie outfits later this month.
On Saturday 20 April, the park is offering £5 admission to anyone who appears at the Staffordshire theme park in a red, blue or yellow onesie – or one-piece outfit.
£10 entry will be offered to anyone appearing in any other colour garment.
The current world record for the largest number of onesie wearers in a single place is 622.
The park’s manager Colin Bryan said: “This is going to be a fantastic event that everyone can take part in.”
“I would encourage everyone to come down to the park showing off their very best onesie patterns for what should be a memorable and record breaking day,” he added.
