How to Act Like a Vampire
If you want to act like a vampire, dress in dark colors like grey and black, and add in accents of white and red. For instance, you might want to wear tight black clothing, black boots, and a black cape with a red lining. When you're around people, stare at them as though you're looking straight through them. Additionally, act as though you are very sensitive to sunlight, and try to maintain a very serious disposition, since vampires aren't known for having bubbly personalities.
Dress in dark colors with red accents. Vampires like dark colored clothing, such as Count Dracula's black silk cape. However, they often accent the dark colors with a hint of red. For instance, Marceline the Vampire Queen wears red boots alongside her grey tank top and tight fitting jeans. Vampire clothing is generally dark (often black), with some color relief (often red, white, or gray). Dye your hair dark on the top and the bottom. Choose red boots with attitude. Wear a grey tank top and then layer on top if it gets cold. If you are in a LARP, you might want to check with the organizers to see if there are any costume guidelines. Choose a vintage style. If you want to look like a vintage vampire character, such as Count Dracula, you'll want to look at some images of traditional vampire costumes. Since the Victorian era is a strong influence, you'll want to choose dark colors and traditional attire, such as a three-piece suit for men. If you are dressing as a male vampire character, you'll definitely need a cape, vest and possibly a tuxedo. If you are dressing in a female vampire costume, you may need an elegant dress, belt and capelet. Try a burlesque style. You can combine the art of burlesque with vampire style. For instance, actress Heidi Klum wore a cobweb cape with a bleeding heart on her corset at a Halloween party. To achieve this look, you'll need red lipstick, eyeliner, heels, and red nails. You may also want a cobweb cape and some high red boots! Vampire clothing is often sexy, so you could try a burlesque look. Put on your fangs. You'll want some vampire fangs to show that you mean business! You can get vampire fangs at most costume and party stores. You could even try the dollar store. Wait until you have applied your makeup to put on your fangs. Wear a cape if you want to look like Dracula. A large cape is a traditional item of clothing, especially for dracula characters. You can find dracula capes in costume stores, especially if it is getting close to Halloween, as well as online. One alternative to wearing an actual cape is to wear long, flowing or billowing coats. If you're doing a fancy dress vampire, black bat or spider broaches add a nice touch. Apply a white foundation. Load your makeup sponge or brush with a white foundation. Pull back your hair so that it doesn't get in the way. Wipe the foundation over your entire face, as well as your ears and neck. You could also apply some gold eyeshadow underneath your eyes. Paint dark and pointy eyebrows. Use a white eye liner pencil to erase outside edges of your eyebrows. You'll want to cover over the last inch of your eyebrows, where they curve down around your eye sockets. Then, use a micro detailing paint brush to draw your vampire eyebrows. Apply some black paint to the paint brush. Paint the outside of your eyebrows so that they go up to a point. Paint a widow’s peak above your eyes. You can use either a black makeup pencil or a brush with black foundation. Draw a widow's peak above your eyes, so it looks like your eyebrows are very dark and pointy. Apply red eye liner to the top of your eyelids. Use a small brush to apply some red eyeliner to your eyelids. Concentrate on the edges of the eyelids, so that you have a hint of red in your eyes. Then, paint your eyelashes with black mascara. Wear enough eye makeup to look sultry and mysterious, but not so much that you look like you just lost a fight. Whereas some vamps like to use black eyeshadow, others prefer neutrals. You could put some shiny green eyeshadow on the corners of your eyes.  Paint your lips blood red. Crimson or red lips are important for a vampire, since they make it look like you just fed on some fresh blood. Choose your favorite red lipstick, preferably a darker shade, and apply it to your lips. Girls can use red or purple lipstick to achieve the right effect, while guys can use a little lip stain or fake blood to get the same look. Paint tears falling from your eyes. Apply black makeup to a fine detailing brush. Paint lines coming down from your eyes in a cobweb formation. Add some red paint to the brush and apply little red tears at the bottom of the lines. Paint some blood falling from your lips. To imply that you recently drank blood, paint some blood falling from your mouth. You can use your fine brush and some red makeup. Alternately, you can apply fake blood. Figure out which vampire you want to play. If you are participating in a live action role playing game (LARP), you may have already been assigned a particular vampire to play. However, if the event is more open-ended, you may get to choose a particular character. If you are not sure which vampire you could find some inspiration by reading some vampire books or watching a vampire movie: Read John William Polidori's The Vampyre. Read Bram Stoker's Dracula. Read Stephenie Meyer's Twilight. Check out Anne Rice's The Vampire Chronicles. Watch a vampire themed television show, such as Buffy the Vampire Slayer, Angel or The Vampire Diaries. Watch a vampire movie, such as Nosferatu, Interview with a Vampire, The Lost Boys, Blade, Vampires, or From Dusk Til Dawn.” Play “unfair” as a vampire character and fair as a player. During the LARP, you should always have a reason for making a move against another character in the game. You should always play fair and avoid cheating. That said, you should have fun playing the role of vampire, which may include cruel or “unfair” things, like blood sucking or killing another character. Highlight the narcissism of your vampire character. Vampires are typically depicted as narcissistic or self-serving. To highlight this trait, try walking with an air of authority, with your shoulders back and your head held high. You should only be interested in talking about yourself. You should only become animated during your own speeches. If anyone else dares to open their mouth, you should adopt an expression of boredom and disdain. Whenever someone you don't approve of is speaking, you should adopt an expression of distaste and look down your nose at the speaker. Know your character. By knowing your character, you can respond quickly to other players in the LARP. You can improvise and have fun! For instance, your character probably has an ability to heal rapidly. Vampires can be brought to the very brink of destruction, only to be resuscitated and restored to their former glory by a few drops of blood. Try speaking in a low voice. As depicted in vampire movies, a low speaking voice is typical of vampires. Work on your soul-piercing gaze. If you are taking inspiration from a film like Dracula, you should work on your soul-piercing gaze. Try to look right through people. To achieve this effect, you should practice an unblinking gaze which you can hold for what is seemingly longer than humanly possible. Don't be surprised if people consider you to be "off with the fairies" rather than perceptive; it's a hard look to pull off, as sometimes you can look dazed rather than intent. Act out your aversion to sunlight. If someone opens the curtains or you're forced to walk outside during the day, you should hiss and draw your cloak protectively over your face. You should also claim to be highly photo-sensitive and prone to sunburn. Vampires can never feel fully at ease during the day. Once night falls, however, you can relax and be your normal fearless self again. You are master (or mistress) of the night. Maintain a serious disposition. Vampires are not known for their bubbly, fun personalities. They are serious and contemplative, without time or patience for frivolity. As seen in the movies, a vampire should be withdrawn, sullen, demure and silent. Vampires don't giggle either. If you must laugh, aim for a dark chuckle or grunt of amusement.
