[unknown] you have to sponsor events..for that you got points and every week these points are counted and you got mistery boxes (according to your points 1-2-3 or more...and other rewards)and these mistery boxes contains pieces of this outfit and flowers too
Go to events and there you will find an icon for hall of fame in the up left corner and you can read more in there...and in the sponsor events too
Good luck🤩✨️✨️
