The following are the costumes available to Tina Armstrong in the 2011 Nintendo 3DS title, Dead or Alive Dimensions.
Initially, Tina had three different costumes, with two default costumes and one unlockable costume. However, with the release of the downloadable content, Tina now has five costumes overall, with two different DLC costumes.
For her costumes, Tina only has one brand new costume, though technically it is a redesign of her first costume from Dead or Alive 2.
