List of Zim's disguises.
Human Child Edit
Zim's most used disguise: It consists of two purple contacts and a black bouffant wig.
Old Man Edit
Zim uses this disguise whenever he must go long distances away from his base.
The alien uses this disguise when he wants "to appear like a normal human".
The Bear suit was seen at the beginning of Battle of the Planets, when Zim contacted the Almighty Tallest. It is unknown why he put the Bear Suit on, and what he did with it (although it may have been a reference to Jhonen's comic doubleshot I Feel Sick, in which Tenna is seen wearing a similar bear suit to Zim's).

Count Ghostula would have been in the unfinished episode Day of Da Spookies! It is a disguise that makes the wearer invisible. It sometimes gets stuck, as seen in Day Of Da Spookies. Zim, GIR and Minimoose use this disguise to trick Dib in to thinking he is a ghost and humiliate him in front of the media when the "ghosts" are revealed to be frauds. It's the second parody of Count Dracula seen on IZ; the first being Count Cocofang.
