Assassin's Creed: Revelations outfits

In Assassin's Creed: Revelations, several outfits are available for Ezio Auditore to wear. Currently only four of Ezio's outfits have been revealed.

Plain Robes
Color: Dark grey and navy blue, with fur padding under the bracers and on the shoulder. There is also a cape in some concept art, and the E3 cinematic trailer, though in the gameplay video, it is missing.

It is currently unknown how Ezio came to wear this set of robes.

Turkish Assassin Armor
Color: Presumably green with orange.

This outfit is only available when purchasing the Special Edition of Assassin's Creed: Revelations, and is available in single-player mode. This implies it will be a cosmetic skin only.

Armor of Brutus
The Animus Edition of Revelations includes the Armor of Brutus from Assassin's Creed: Brotherhood, available in single-player mode. This implies it will be a cosmetic skin only.

Altaïr Skin
Pre-ordering the Collector's Edition of Revelations in the UK gives access to the skin for Altaïr from the original Assassin's Creed (also seen in Assassin's Creed II and Brotherhood) in single player.

The Animus Edition for Australia, however, lists the skin as being Ezio in Altaïr's Robes and indicates the skin is for multi-player, not single-player. This is apparently a regional difference.

Trivia

 * The plain robes has changed slightly during development. Whereas it was dark grey and navy blue in the concept art, the version shown in the E3 gameplay demo appeared to be faded black. The Masyaf seal on the stomach has also been changed to the Assassin insignia.
