I think there should be a function in the game where you are allowed to unbind costumes. (With a reasonable CE Price of course) I think that would be very nice because I feel like that some costumes such as the Bombmasks are very hard to get and it all leans on luck whether you get it or not. I have been trying to get the Frosty Bombmask for weeks already and I still have no luck. I feel like it would be much easier if I can just buy the mask off of someone else. I hope the creators of Spiral Knights can take this suggestion into consideration.
