Dressing up as a Particular Character

You can also dress up as a particular character from Slytherin such as Crabb, Goyle, Malfoy, or Millicent Bulstrode. All you need to do is buy a men’s or women’s Slytherin costume, and then do your hair like the particular character. If you are good at imitations, even better!

Face Painting the Slytherin Colors

Now, for this, you won’t even have to buy a robe. But if you want your appearance to be really scary, you can buy a Slytherin Halloween costume and then paint your face with Slytherin colors. But remember z the colors should not contain any harmful chemicals and remember to wash them off, completely, after the event ends.

Dressing up as Salazar Slytherin

Well, this will take quite some effort. You will need a Slytherin robe, a goatee, and a really solemn face to go with all this. You will also need a lot of grease or hair wax to maintain that scary backbrush. You can also do an accent, for added effect, or speak Parseltongue.

Dressing up as the Dark Lord Himself

Well, beware! This is going to be quite scary! And so will be the number of prosthetics and makeup required and the dedication required to maintain and pull off this look. But this will probably be the best Slytherin Halloween costume of all. You can ask your friends to dress up as the Death Eaters.

Pulling off “The Snape”

Well, if you go for this, remembered, he is one of the most beloved in the series. This is best suited for those with long, black hair.

You can put on some makeup, to make you look as pale as Snape himself.


Well, just buy a Slytherin Halloween costume or a Slytherin robe and take care of the rest on the spot. Improvise.
