This is a list of Mickey Mouse's forms and costumes in the Kingdom Hearts series.
Game clothes
Kingdom Hearts Birth by Sleep version
While training under Yen Sid during Kingdom Hearts Birth by Sleep, Mickey's outfit is virtually identical to the way it looks in Kingdom Hearts II, except for the color: Mickey's clothing is colored in greyscale, losing all the colors it had, save for black, white, and grey, making it similar to Sora's Final Form outfit in Kingdom Hearts II. He also attacks using the teeth of his Star Seeker as opposed to the broad edge of the Kingdom Key D in Kingdom Hearts Birth by Sleep, adding more contrast between his appearances in both games.
Kingdom Hearts version
Although Mickey is only seen as a silhouette near the end of Kingdom Hearts, Mickey sports his classic Disney attire consisting off a pair of white gloves, red shorts with two white buttons in the front, and yellow shoes. This design was eventually used as a base to create Sora's outfit in the first Kingdom Hearts. Since Mickey was only shown as a silhouette, Jiminy was incapable of recording the King's outfit in the journal.
Kingdom Hearts: Chain of Memories version
In Kingdom Hearts: Chain of Memories, Mickey wears a black vest with white lining, two yellow buttons near the bottom, and a zipper that only reaches about halfway down the vest. Under this vest he wears a short-sleeved shirt that is seems to be the same black, white-lined color scheme as his vest, though the cuffs of the sleeves are red. His pants are red and quite baggy. The pockets have white lining. Similar to Goofy, the front of Mickey's pant legs are pulled up slightly by elastic, blue straps. Mickey's shoes here are also yellow, but the tips and lower halves are black and the soles are white. Each shoe has two blue straps that intersect over the top of the shoe.
Kingdom Hearts 358/2 Days version

During Kingdom Hearts 358/2 Days, Mickey wears the black coat, gloves, and shoes that Organization XIII members wear. Though largely the same as the other coats, Mickey's apparently has contortions in the hood for his ears, and the drawstrings on his version sport Hidden Mickey symbols on the tips. He also wore the block coat in the early stages of Kingdom Hearts II.

Halloween Town version
Kingdom Hearts II
Timeless River version
When Mickey was a resident of Timeless River, he is colored in grayscale like the other inhabitants of the world. He is modeled after his appearance in older Disney cartoons like Steamboat Willie. Mickey's face is white and his eyes are simple black ovals. His fur is black, as are his ears, which are simple black circles. Like in the older cartoons he is from, no matter which direction Mickey himself is facing, his ears are always facing the screen. He wears the famous white gloves common to many older Disney characters. His shorts are white and have two buttons on the front. His shoes are also white, and he does not wear a shirt. Mickey also sports a thin, long tail.
