How do I get all the Amiibo Gears in Splatoon 3?

[esther]

In Splatoon 3 you can get exclusive gears from Amiibos, like the previous game.
In Splatoon 2, https://gaming.stackexchange.com/questions/314816 :

To unlock the special Amiibo sets of gear you need to increase your level in Splatoon to level 7 which unlocks you the shirt of the amiibo sets.
To complete the set you need to get to level 10.

As far as I know, you always get the first piece of gear without doing anything special.

Is this still correct for Splatoon 3? Do I just need to level up in order to unlock more gears?

If you haven’t already https://gaming.stackexchange.com/questions/399341/how-do-i-get-all-the-amiibo-gears-in-splatoon-3/399399#comment561199_399399 , Amiibo gifts seem to be related to how many battles you've completed since scanning the Amiibo.

I scanned several amiibos at level 18 and each one only gave me shoes. When I scanned them a second time they had dialogue telling me they would have more gifts if I came back after some battles.

They gave me the rest of their gifts when I rescanned my Amiibos two days later at level 21. .

The amiibo then let me know they had given me all of their gifts.
