List of Mario Tennis Open Mii gear

In Mario Tennis Open, the Mii can equip gear in order to alter his or her statistics. The gear must be bought with coins earned from the Special Games from the Clubhouse. They must first be obtained by playing matches against opponents, which unlocks a random piece of gear. Gear based off characters will reflect the characters stats. Costumes may also be unlocked by clearing certain conditions, such as Starring a character or collecting a certain amount of coins. Statistics can altered in 9 different ways, each in three categories. These are shown in the form of pie charts.

Power
 * Serve: The strength of the serve.
 * Stroke: The strength of a hit after the ball has bounced.
 * Volley: The strength of a hit before the ball has bounced.

Spin
 * Side: The left or right curve after the ball has been hit.
 * Topspin: The amount of spin placed on a Topspin shot. The higher the stat, the higher and faster the Topspin.
 * Slice: The amount of backspin placed on a Slice shot. The higher the stat, the slower and lower the Slice.

Speed
 * Top Speed: The maximum speed of the character.
 * Acceleration: The amount of time it takes to reach the Top Speed.
