I can't open 3 secret outfits. it is unclear what kind of SO-03
Hello,
I'm sorry this isn't clear.
SO-03 = Secret Outfit 03.
To unlock this outfit you will need to equip yourself with 3 elements (top - bottom - shoes) which resembles the SO-03 thumbnail.
Thank you for your comment and I hope you manage to unlock this outfit (there will be more soon...)
