Tall and fair like most of the Noldor, Aratinwe moves with the grace and confidence common to his people.  His hair is thick and long, dark reddish-brown in color, swept back away from his face.  His features are striking, if somewhat severe, though not unknown to house a bright and mirthful smile.  His eyes, a piercing sky-blue flecked with green, have a tendency to roam about his surroundings, calmly appraising his environment.  Despite his habitual vigilance, he often loses focus on his surroundings, slipping into periodic ponderings.

Aratinwe more often than not wears his armor during the daytime and anytime he is away from Rivendell, as he is so accustomed to it as to be somewhat uncomfortable without it.  It is a beautifully crafted set of platemail, dark steel with crimson, backed by fine chainmail, and fitted perfectly to the elf's formidable musculature.  He prefers a hood and cloak to a helm in all but the direst of situations, favoring a dark crimson cloak with accents in fiery orange most days.  During the eve and mornings, which he most often spends in the Last Homely House or near it, he favors a rich black and gold robe and cloak, warm and soft cloth crafted for the utmost comfort.

Whenever he strays from Rivendell, he rides upon a young bay stallion he calls Thalias, whom he can also be seen taking out to graze in the early mornings and late evenings.  Thalias is a loyal and spirited steed, possessed of a stalwart bearing, and all but fearless when reassured by Aratinwe.  He is barded in white and gold, an elegant and cheerful design, and is kept nearly as well as he keeps his rider.
