The walking dead that have only basic motor and mental function - their only purpose is to walk the earth in search of is food. Of course, we don't have to mention that their favorite meal is human flesh and blood. Here's how to put such an apoplectic costume together:
First, use makeup to lighten your skin (and make it look pale or even grayish). You can use some color or ketchup on your lips and around your mouth in order to get fake blood stains.
The clothes don't really matter, but if you are wearing a shirt try to make it look messy, leave it out of your pants partially and leave your shoes untied. Of course a ripped shirt can make the effect look more real.
Furthermore, you can behave like a zombie that hasn't eaten for a while. In order to achieve this look, use even lighter colors on your skin (some parts can be white), forget the fake blood and just walk slowly, without expression on your face.
There are many things that lead to the creation of one zombie and one of the most common ways is to get bitten by a zombie. A person that is turning into a zombie has a specific appearance and you can use it for your Zombie costume for Halloween.
In this stage, people are slowly turning into zombies who can be easily seen by the look of their veins (they are becoming darker and more noticeable so use some colors to make them look like that).
This means that it is better to use some shirt without sleeves. Emphasize the veins on your neck and face too. Of course, don't forget to highlight the place where you were bitten (in most cases your neck). While it's true that zombies are dead and not getting older, it is also true that their bodies slowly degrade. So, another good idea is to become a rotting zombie. Expose some parts of the body where you will show your rotten skin. Use stickers that represent open wounds or bones.
Finally, you can use some popular movies, TV shows or games to get inspired for this Halloween costume. For example, try to look like the zombies from the popular game called Plants vs. Zombies or the zombies from the movie World War Z, Resident Evil, The Walking Dead, Dawn of the Dead, 28 Days Later etc. Using some of these costumes for Halloween will surely make this celebration even more fun.
Sometimes just simply being undead isn't enough, and people need to see exactly how you died in the first place. Over the years, the trend with zombie movies has been to get more and more graphic, so you can serve as a perfect modern example of what this genre has become. For this, you're going to need some latex prosthetics. These are fairly inexpensive for our purposes, and it's not hard to source a fake wound kit.
As with the simple zombie outlined above, give yourself a pale foundation that makes you appear dead, but this time add some gashes on your face and body. Have some fake blood dribbling from your wounds as well for added dramatic effect.
If you really want to get into it, you can also make some fake guts out of red play-doh or even rolled up strips of dyed paper and have them hanging out of your shirt. For your clothes, make sure that they are ripped and covered in blood. Besides that, just use your imagination. What kind of person were you before you joined the ranks of the undead?
If you want to pay homage to a certain time period such as, World War II, you might want to give the historical zombie costume a try. You can be an undead prince or lord from feudal times, or you can try your hand at being a zombie soldier that rose from the dead years after being gunned down.
If you're going with this option, follow the usual pattern of giving yourself a corpse-like makeup job, but be sure to make yourself look a little more decomposed. Add some clothes that are typical of the time period that you're going for, and make sure they look a little bit old and tattered.
This kind of costume goes especially well if you and your family are trying to keep to a particular theme. For example, if your theme is "the 1960's," you can be a zombie hippie or something similar.
