There are two genders, Male and Female. There are not many differences between these two characters, however male players can have beards while female players cannot. The gender is decided in the Tutorial Island when first logged in. It may be later changed by visiting Make Over Mage in southwest Falador and paying him 3,000 coins.
Both male and female players can wear a male Plate Mail Bodies.
Only female players can use a female Plate Mail Tops.
Male characters also have a default shirt different to female characters.
