Each of my sims dressed up in a seasonal/wintery themed outfit for the festive grotto:
Rhydia's theme was Snow and Snowpals.
Leoni chose Christmas/Winter Fairy.
Norrell went with Santa's Elf (Norrell: "That's 'Santa's Super-Good-Looking-And-Probably-More-Intelligent-Assistant' actually.")
Tadeo was inspired by the Movies which get shown every year on TV at Christmas, and dressed as a notorious pickpocket character* from the musical 'Oliver!' *(The name is censored? Why?)
Samphy's theme was Festive Reindeer.
Kio was inspired by his love of Christmas Lights and dressed in celebration of this.
Jiya also came as a Christmas/Winter Fairy, but with a more nature-inspired look.
Ikkanu's look was inspired by his favourite thing to be near at winter time, a warm Fire.
