Let's be honest, we've all done it:

1. Cat

Is it even Halloween if you don't see at least one cat costume?

2. Vampire

Just throw on some fangs, fake blood, or put some holes on your neck to prove that you're an undead bloodsucker.

3. Witch

Like the cat and the vampire, the witch is also a really easy costume, all you need is a hat!

4. Princess

Maybe you were a princess when you were younger, or maybe you never stopped dreaming of living in a castle. Regardless Halloween can be your day to dress like royalty.

5. Exactly what everyone else was

There's nothing like going out on Halloween and seeing versions of your costume around every corner.

6. Whatever your parents put you into for your first halloween

We were all a pumpkin or a teletubby once.

7. That one year you went all out

Which is every year if you're Heidi Klum. And yes all these photos are Heidi Klum.

8. Nothing

Of course, sometimes life happens, and maybe you were too busy, or maybe you just forgot, but we've all rocked the no costume look at least once.
