TODAY: It’s Halloween, time for youngsters to don costumes and seek treats, under threat of mysterious tricks for a lack thereof.

We’ve found the 10 most popular costumes through the years to share. Consider it our “monster mash.”

10: Frankenstein’s monster:  The costume often features black hair, green skin and bolts in the neck as Boris Karloff is famously depicted in the 1931 Frankenstein movie.

9: Ghost: The white bedsheet draped to the ground with two holes for eyes and a black mouth is one of the most iconic sights of Halloween –– even Spongebob and Charlie Brown have sported this favorite costume.

8: Mummy: Say what you will, but sometimes even a monster wrapped in toilet paper can give us the creeps.

7: Vampire: The sunlight and garlic-fearing monsters who notoriously bite the necks of mortals are a common sight around the area during Halloween time.

6: Grim Reaper: The black-cloaked, scythe-wielding skeleton’s reputation as a symbol of death seems to have surfaced in the 14 century –– the century of the Bubonic Plague epidemic that wiped out one-third of Europe’s population.

5: Skeleton: Need we say more? Throughout the years, this costume has been the go-to for giving others chills to the bone.

4: Zombie: As one of the most popular Halloween costumes, especially as of recently, thanks to The Walking Dead, the 1932 movie White Zombie was actually the first film to feature the ghastly creatures.

3: Pirate: Made famous by people such as Johnny Depp, Blackbeard and even baseball players in Pittsburgh, this costume is suitable for people of all ages and never disappoints.

2: Clown: To most, this one is often the creepiest. But the compilation of face paint, wacky clothes and big shoes has remained very popular.

1: Pumpkin: This costume is often a popular one for toddlers or babies celebrating their first Halloween.

Regardless of the costume, youngsters will be out in force today. Please use caution when traveling, and ensure all have a happy and safe Halloween.
