You can get pins in different ways:
- You can win pins in room seasons, Trials of Style, etc.
 - Some pins will come with purchases.
 - Upgradeable pins are achievements you can earn from in-game activities.
 
Upgradable pins have different backgrounds depending on the tier. Tiers are (from the lowest to the highest level):
- Bronze
 - Silver
 - Gold
 - Crystal
 - Black
 
The higher the level, the harder it will be to unlock. You can check which pins have been unlocked by checking the new pins page.
