This thread is to tell people who doesn't know that if you prestige, you will lose:

1. All Coins
2. All Parts
3. All Stickers But You get:
4. New Stickers
5. New Body Parts
6. Badge You Keep:
7. All gems
8. All Ratings
9. All skills

Now, since you know what will happen when you prestige, it will be "advantageous" if you sell all your parts and stickers immediately when you reach Stage 24 and trade "ALL COINS" (since you will lose all of them) to buy Cats Hats since you can keep those permanently after prestige :D
