There are quite a few bonus costumes to unlock in Rayman Legends.
To unlock the bonus costumes, you just need a certain amount of Lums to purchase them from the Heroes Gallery.
I have noticed that some of the costumes cost different amounts on the WiiU compared to other consoles for some reason, so I’ve made two separate lists.
