Page "Banshee" Paragraph 12

Banshees are frequently described as dressed in white or grey, often having long, pale hair which they brush with a silver comb, a detail scholar Patricia Lysaght attributes to confusion with local mermaid myths.

This comb detail is also related to the centuries-old traditional romantic Irish story that, if you ever see a comb lying on the ground in Ireland, you must never pick it up, or the banshees ( or mermaids — stories vary ), having placed it there to lure unsuspecting humans, will spirit such gullible humans away.

Other stories portray banshees as dressed in green, red, or black with a grey cloak.
