Top tips for being safe

  • We’d recommend using LED tea lights for your pumpkins rather than traditional tea lights to avoid naked flames.
  • If you do choose to use traditional candles and tea lights, please take care around open flames. Keep all burning candles off the floor and out of the reach of children.
  • Our fancy-dress lines are tested at the manufacturing stage to make sure they’re safe and comply with all legislation.
  • Our children’s Halloween costumes meet the European Toy (EN71) safety standard and the British Nightwear Flammability (BS5722 Test 3) safety standard – the toughest standard that currently exists.
  • Please note, fire testing excludes socks and tights with some costumes.
  • When trick or treating, plan a route in advance, go in groups and let someone know where you’ll be.
  • Visit houses that have their lights on. They’ll usually have a pumpkin or Halloween decorations on display, and never go inside someone’s house.

A bit of Halloween history 

So how did we come to celebrate this spooky holiday and why is it called Halloween you ask? Well, it all began a long time ago by the ancient Celtic religion as the festival of Samhain celebrated in Britain where the Celts would light bonfires, wear costumes and hold big parties to scare off any ghosts and spirits, sound familiar? It wasn’t until the 8th century when Pope Gregory III declared a 3-day observance dedicated to remembering the dead; landing on November 1st as All Saints’ Day. Making the night before All Hallows Eve (Hallows means saints) and this is how we came to call October 31 Halloween!

Halloween traditions

Many of the Celts Samhain festival traditions were adopted by the All Hallows Eve way of celebrating which has been passed down to today. The lighting of bonfires and dressing up in costumes can all be seen today, except in the 8th century they called it ‘guising’ and ‘souling’. Guising basically means wearing a disguise AKA costume and knocking door-to-door for apples and nuts and Souling is when the traditional soul cake, a cross between a biscuit and fruit scone would be eaten and given out to people who knocked on doors to sing and pray (like Halloween carol singers if you like). The only difference is today we call it trick-or-treating and prefer chocolates and sweets instead of fruit and nuts.

So whatever Halloween tradition you’re going to partake in, let us help you get it right. Whether you’re planning on staying in and watching a horror film, putting on a killer Halloween party or putting on a costume and trick-or-treating the night away, we’ve got everything you need right here in our frightfully fantastic Halloween range to make sure you have the perfect Halloween!
