I'm a nurse. I draw blood all day. Guess what I dress as!!! Actually, I go for the subtle look. I have theatrical fangs that attach to my eye teeth. They aren't very big. I can talk and even smile with them and they can't be seen. I love going into the lobby and getting a patient then as I walk them to my lab I turn around to the family and smile really big. The gasps are totally worth it. Then I send the patient out with two red dots on their neck.

Note: I only do this to my well known and easy going patients/families. If I have a new or sensitive patient I keep the fangs completely under wraps.
