You can get this pin by getting 5 hearts in the Trial of Style. The more often you get 5 hearts, the higher the level of the pin will rise.

This is the amount you need:

Level	Receive 5 hearts
	1x
	5x
	30x
	75x
	250x

After reaching the 5th level, you can level this pin again with the same number. After that, the color no longer changes, but a number appears on the pin. This shows other users how many times you have reached the last level.
