They drop frequently so you'll get more than enough. Apparently some people say they will be used for alchemy to get a certain event kin. So that'll be cool. I wouldn't count on it but you never know. Everything I am wearing is Spirited 2k15 except for the eyes which are from Light Healer. But that's about all I can really think of.
Thank you! It is the event clothing you get from lake kindred. (Not all because the layering is off for certain items.) These are obtained in the game while the other color is red and those are obtained from caroling.
