The one time of the year when it’s guaranteed almost everyone will be in some kind of fancy dress if they are attending a party.
Even in the UK, this trend which like photo booths, started more in the States than here, is becoming more prominent every year. I recall not that long ago pretty much all that would happen was kids trick or treating in the streets. Suddenly every greengrocer & supermarket is filled with pumpkins & almost every shop you enter has something hallo-weeny for sale.
With the abundance of costumes, masks & make-up this is also the perfect opportunity to hire a photo booth, especially with a custom designed layout available which would be unique to your party!
