A favoured time of year for those partial to a bit of dressing up and make-believe, Halloween is just around the corner.
And if you're stuck on deciding what to wear for the spookiest day of the year, fear not. Stylist.co.uk has been busy consulting the shopping experts at Lyst, the world's biggest online fashion site, to discover the most popular costumes for 2016.
After assessing over three million products sold in 12,000 stores worldwide, these are the definitive eight outfits that are being shopped the most this year.
So whether you want to imitate a favourite TV character, or opt for a classic cat costume, let this be your guide...
Beyonce in Lemonade
Ever since Beyonce's visual album Lemonade dropped in April, searches for ruffled yellow dresses have increased a massive 120%.
But if parting with thousands of pounds to get your hands on Bey's yellow Cavalli dress, above, for a Halloween costume sounds a tad excessive, look no further than the high street. Zara have come up trumps with this £50 version (below), currently being viewed once every 20 minutes.
The red trouser suit worn by Hillary Clinton during her first televised Presidential Debate against Donald Trump (above) caused a huge spike in searches for a similar look. Clinton is set to be such a popular look for Halloween that this £55 Asos cropped red blazer co-ord has already sold out.
Searches for a truly terrifying Halloween Trump wig have been climbing steadily over the past few weeks, while the Presidential Debate has seen an increase on page views of 60% for this familiar-looking £3 red cap from Topshop. Surely the easiest Halloween costume ever.
Eleven from Stranger Things
Prepare to see a whole host of Eleven lookalikes this Halloween, as the masses pay tribute to everyone's favourite Netflix show, Stranger Things.
Lyst have seen a huge spike in searches for the components of Eleven's iconic look: this pink Peter Pan collar dress (£35 from Asos) was viewed once every three minutes until it eventually sold out, while there has been a huge spike in searches for blue jackets and a 34% increase in sales of tube socks.
Yes, really. Festival season may be over but Lyst reports that sales of headdresses are still soaring, with flower crowns, dog ears and the golden beauty filter tipped to be popular looks this Halloween. This Eugenia Kim gold butterfly tiara (£55, below) is currently the most-viewed hair accessory.
The late, great Bowie continues to reign supreme in the fashion stakes: his red boots have become a street style staple and one of the biggest footwear trends of A/W 2016. Red, pointy ankle boots have been selling out for the last month, across designer and high street stores, according to Lyst. Pair yours with some zig zag make up and you'll be good to go.
Harley Quinn was the most popular Halloween costume in 2015, before Suicide Squad had even been released, and evidence suggests she could take the crown for a second year running.
Lyst reports that searches for red and blue souvenir bomber jackets are growing 25% week on week, while there were 12,000 searches for Harley-inspired studded belts last week.
Dressing as a cat remains one of the most popular, and easiest, Halloween costumes. Searches for cat ears are already on the rise, with Lyst reporting that lace styles are the bestselling so far, with sales of these £8 River Island ones (below) seeing a big spike.
All you need to decide is whether you want to go full-on Gretchen Wieners by pairing them with a black catsuit (above).
