Like some her Telerin kin, Faerinil has straight and long, silver hair which she usually tie just around her head so that they do not fall into her face. Her skin is rosy pale and not easily tanned by sunlight. Only slight redness can be observed when longer in the sunlight. Light grey is color of her eyes, almost platinum in certain light. Some would say she has glance of serenity in her eyes. 

Blue and yellow are her favourites and she adorn herself in colors of the sea and sand. When on travel or in battle, Faerinil prefers freedom of movement and wears tunic or hauberk with trousers. In times of peace, she can be seen in dresses or robes.

As many of the Calaquendi, her spirit emanates an aura of light, which is like beacon of hope in both battle and healing. Faerinil's voice is usually quite gentle and soft, however can be resonant if needs be.
