Clowns will always be scary, but Pennywise is an especially popular costume idea this year because of the movie.

So long as you get this in the right size (which some customers have warned about), you shouldn’t have any problems with staying comfortable while dressed as a killer clown. Plus, unlike the “sexy” costumes which leave little to the imagination and too much open to the elements, you should stay warm enough in this. 

If your goal is to scare the s@#$ out of people with your costume, then you’ll definitely get some good mileage on this costume choice year after year.

It’s pretty expensive. If this one isn’t in your budget (don’t forget about the extras you have to buy), you can always look around at other killer clown costumes available.

This horrifying mask is fairly comfortable, but it gets hot after a while. Make sure you take it off whenever sweat starts pouring down your face.
