The Helsing is named after Van Helsing the Vampire killer, and is a type of body armour.
As the humans know the best way to kill us is a stake in the heart or cutting the head off. This is what they always go for - along with garlic, which is a myth created by people wanting to sell more garlic, and and holy water, which is a myth created by the church seeking donations for repairing their roofs.
Humans are a little stupid over this. As a species Vampires are very intelligent and long-lived and it didn't take us long to work out that we live a lot longer if we can stop people sticking a sharp piece of wood between our boobs.
Helsing Armour is a metal plate which fits over the heart and is fitted as standard into clothing such as "The Hunter" and "The Fighter," or added as extra detachable plating. It is worn under the shirt of the Male, and cloaks have high metal collars so to protect the neck from a sword blow. Females can have a Helsing fitted into a bodice, or have it made to look like an ornate bra.
Helsings are always designed for positioning over the heart area of the chest to make it impossible for the wearer to be stabbed in the heart with a wooden stake. It would even stop silver bullets, swords, knives or in the case of one particular nasty killing in a Vampire film, stiletto heels. Vampires are traditionalists but we are not stupid, we've seen all the films on the subject and are normally the people who laugh in a cinema when a movie Vampire did something so stupid as to let his lunch kill him.
You do not have to have expensive clothing like the 'Hunter' tight and sexy and wow does it get the food drooling ... when going out for a quick snack. You can just wear your normal clothes, and then you can take the prey by surprise. While it is looking at your legs or looking down your top you can be getting out a packet of tissues to clean yourself up afterwards.
It is very eye catching and visually pleasing for watchers to your hunting, if you wear a light flowing dress. This is always fashionable due to the fact that it rises into the air when you spin around, giving the prey and viewers a nice flash of leg. But no matter how proud you are of your family brand, in these circumstances the best thing to wear underneath is a tight fitting pair of black cycle shorts - see the movie 'Blood the last Vampire' where you can see 'Saya' leap, spin, somersault and kill without any worry of showing off her brand to strangers. Or even the fact you are in need of a personal fainforest trim +++++++++++++
