Ashely Benson as Hanna Marin

Fashionista of the show Hanna showed up as the spitting image of Marilyn Monroe to one Halloween party.
Shay Mitchell as Emily Fields

Emily's superhero Barbarella costume came in handy. This was the episode where she had to save Aria's life!

A masquerade ball, PLL style! It's no surprise that Hanna dressed as Juliet while Aria channeled her inner edginess in red and black.

Everyone loves a good hoedown! Spencer, Toby, and Emily show how a cowgirl/cowboy is one of the easiest costumes to pull off.

The girls' season 4 Halloween costumes were amazing and very fitting for the Victorian-themed party they attended in Ravenswood. Aria showcased her love for accessories, while Emily worked the menswear trend.

In true Spencer Hastings style, Spencer shows how modesty and sophistication can still lead to a killer costume!

All signs point to...EzrA?! This soldier suit with the gas mask is by far one of the scariest Halloween costumes yet! Maybe because we know the face behind the mask...
