The Plastics (Mean Girls)

Though the Plastics do wear some memorable Halloween costumes in Mean Girls, their “On Wednesdays, We Wear Pink” look makes a great group costume.

Each of the Plastics has their unique way of pulling together a pink look. Regina George’s style is edgy with a black skirt; Karen is the most feminine in a baby pink matching sweater and skirt; and Gretchen is more put-together with a plaid skirt and Starbucks drink in hand. Naturally, Cady is trying to figure it all out in her oversized pink polo.

These looks would make the perfect group Halloween costume, as each of you and your friends can style the look in your own way. Together you will be so “fetch.”

The Heathers (Heathers)

The Heathers, another mean group of girls, are very well known for their ’80s getups and their primary colors. They’re another example of a great girly Halloween costume inspired by the movies.

Since the ’80s are coming back, a Heathers costume is easy to do. Grab an oversized blazer with shoulder pads, a mini skirt, and a scrunchie, all in a primary color.

This would also be a great costume to get your girlfriends to join in on. Each of you could be your own color, and you can all rock some ’80s fashion together.

Olive Pendergast (Easy A)

Though at the beginning of Easy A, Olive wears normal clothes, by the middle of the film, she switches into some scandalous lingerie-inspired looks. The look above in particular makes for one of the easiest Halloween costumes from movies.

Now this look might not be the easiest to wear. But don’t worry about going full on Victoria’s Secret, as you can wear any semi-sexy all-black outfit and you will look the part.
