In Mortal Kombat (aka Mortal Kombat 9, 2011 Version) for the PS3 and Xbox 360, there are a lot of alternate costumes you can purchase in the Krypt from the Extras menu.
In each land of the Krypt, there are numbered markers that you can purchase. Once you purchase them, go to the Nekropolis and click on the corresponding character in order to have access to the costume you purchased. On the character selection screen, you need to press Start in order to change a characters costume once you’ve unlocked them.
