You cannot get it after the event. However, what I'm not 100% sure of now that I think about it is whether you must activate it during the event. There's a quest at the campfire after dev 3 I believe that is costume related. You have to do that either way. Then you'd go into the menu where you feed stuff and you'd take your max level mashu with the needed materials. However, it may stay as long as you've completed the quest, leaving you to spend the mats with your max level mashu at your leisure. I don't know.
