Halloween is just around the corner, so you need to get your outfit sorted pronto.

But, whether you like being part of the crowd or can't think of anything worse than costume competition, you need to figure out what most of your fellow Halloweeners will be wearing come October 31st.

Lyst has partnered up with Pinterest to tell the world what they predict what the most popular costumes of 2017 will be according to their search trends.

After crunching data from over 180 millions monthly users worldwide, they came up with this list.

Were you planning to dress up as one of the most popular Halloween characters?

1 | Pennywise

If people make the bold choice to *actually* go as something scary this Halloween (a notion that is becoming increasingly scarce) then the evil clown from the 2017 film It, is what they will go for.

According to Lyst, Pinterest saves for clown make-up and costume ideas are up 941% YoY, despite the film only having come out last month.

So, if you were thinking about going as the creepiest clown ever then grab your pom poms, now, because they sure to be selling out soon.

2 | Belle

Back in spring, La La Land and Beauty and the Beast both triggered a swift spike in searches for yellow dresses.

Now Halloween is coming round, however, it is Beauty and the Beast characters that have gotten a 680% pinned increase on Pinterest.

It looks like the savvy shopper will be recycling that sunflower-yellow prom dress come 31st October, and you know what? We don't blame 'em.

3 | Baywatch Lifeguard

2017 also saw the long-awaited reboot of the Baywatch franchise. The film release apparently saw an increase of 240% for searches for red swimsuits over the summer.

For those who have managed to maintain a Pamela Anderson-style bod over the summer (not us), whipping out the high-cut swimming costume is an obvious choice this Halloween.

4 | Unicorn

You can't turn your horned head for a unicorn latte or dye-job these days, and you know what? We love it.

This festival season the field were akimbo with unicorn revellers, complete with holographic bodysuits and jewelled make-up.

Accorsing to Lyst, this trend is set to continue through to Halloween too, with searches for 'unicorn' up 130% since May and a 110% YoY growth on Pinterest.

It turns out, this year, unicorns won't be so hard to spot.

5 | Khaleesi

We saved arguably the most obvious for last since Daenerys Targaryen has been everyone's favourite Halloween costume for a few years now. However, with this season of Game of Throne being the last and a 91 percent increase year on year of Pinterest searches, 2017 could be peak Khaleesi.
