Ezio Auditore's robes

So far, Ezio Auditore has worn at least six sets of robes in the memories he is featured in. Ezio has had two customizable sets of robes (customizable through adding armor, changing dye colors and equipping different capes) and two special sets of robes that come with a set of unbreakable armor, which cannot be customized.

Assassin's Creed II
In Assassin's Creed II, Ezio inherited the Assassin Robes of his father, Giovanni Auditore. These robes are symbolic of the Assassin Order, with the beaked hood and the faded white cloth.

Appearance
The standard Assassin robes used in Assassin's Creed II are worn over the top of Ezio's normal clothes and so his boots, trousers and sleeves remain the same. The upper body features a hood with the center shaped to resemble an eagle's head, a feature kept from Assassin's Creed. The hood is connected to the robes, with the torso bearing an open collar.

The lower part of the robes are doubly layered, with the back of the robes trailing down to be longer than the front. Around the waist is a long red sash with belts that are used to store throwing knives, smoke bombs, and medicine. The belt also holds together an ornate Assassin insignia. The robes also have a leather spaudler where a cape is attached, draping over and around Ezio's left arm and shoulder.

Customization
The standard Assassin's robes can be dyed with any color that a Tailor can offer. Armour can also be added, and any combination of Leather, Helmschmied, Metal and Missaglias armor pieces. However, for purely stylistic choices, any combination of armor pieces may be used together if the player does not mind having less (or more) health squares.

Finally, Ezio may choose to wear one of four capes with the Assassin's Robes; the Plain Cape, the Medici Cape, the Venetian Cape and the Auditore Cape, although the color of the Medici, Venetian, and Auditore capes can't be changed.

Assassin's Creed: Brotherhood
After the siege of Monteriggioni, Ezio is given a new set of robes by Machiavelli that are a cross between the Ezio's robes in Assassin's Creed II and Altaïr's Robes in Assassin's Creed.

Appearance
Ezio's new robes show similarities between Giovanni and Altaïr's robes mixed together, as they have a long, layered lower section, although they maintain the open collared torso similar of Giovanni's robes, and include a new closed collar beneath. The hood shape from the previous two games has been kept as well as the wide, red sash displaying the Assassin's insignia and the function of carrying Ezio's throwing knives. The robes continue to feature the cape over Ezio's left arm and shoulder with a leather spaulder (although it is plated in cover art).

Customization
Assassin's Creed: Brotherhood improves the customization system from Assassin's Creed II, with the opportunity to dye the cape separately to the main body of the robe, allowing for many color combinations. Most of the dye colors have returned from the previous game, although some of them have been tweaked, renamed or both.

Again, the armor system allows for further customization, with four new armor sets to replace those of Assassin's Creed II: the Roman, Rondelle, Plate, and Seusenhofer armor sets (having similar stats to the Leather, Helmschmied, Metal, and Missaglias respectively), which can all be used in any combination. The Auditore, Medici, and Venetian capes also return, with the addition of the Borgia Cape, though the plain cape is the only one which may be dyed.

Assassin's Creed: Revelations
In the upcoming Assassin's Creed: Revelations, Ezio has once again changed his outward appearance, having an all-new set of robes that differ greatly from his previous attire.These robes are largely dark grey and navy blue in color, rather than the usual Assassin white. These new robes also have greyish white fur padding on the left shoulder and under both bracers, as opposed to the leather his previous outfits had, and Ezio now wears a dark blue scarf around his neck instead of the open style or collar seen in his previous outfits. It's also missing the cape on the left shoulder that all of Ezio's previous robes accompanied. Ezio's new robes in Revelations are also notably shorter than the robes he had worn in Brotherhood, the overall length of them being closer to the robes he wore in Assassin's Creed II.

The robes also bear the square insignia that the Assassins during the 12th century used at the fortress of Masyaf and a small, unadorned Assassin insignia on the buckle that connects the belts which cross over his chest. There is also an upside down insignia on the tip of the hood.

Trivia

 * In Assassin's Creed: Brotherhood, there is a hidden method in which Ezio's armor can be removed. If the player has the Armor of Brutus worn and returns to Sequence 2, before going to the blacksmith and equipping Roman Spaulders, when they exit the replay of the memory, Ezio will only have the Roman Spaulders equipped. However, if the player goes back to the hide-out on Tiber Island, they can re-equip any armor set.
 * When playing the third Cristina Memory, Ezio is wearing the Medici cape, despite not possessing the cape at the time.
 * On the front cover art for Assassin's Creed II, Ezio is shown wearing a variation of the Metal Pauldrons. However, on the back cover art, he isn't wearing any pauldrons other than the one that came with Giovanni's robes.
