GTA Online contains plenty of secrets and easter eggs ranging from Bigfoot to Aliens — there are dozens of mysteries and secrets.
One of those secrets is the Epsilon Robes (also known as the Epsilon Outfit) which you can unlock in GTA Online. Not a lot of players are aware of this outfit though, since its release with the Arena War update.
In order to unlock the secret Epsilon Robes you simply need to tip the Nightclub Attendant in the restroom 575 times ($1 per tip) for a total of $575. The process is quite lengthy but worth the effort!
Fun fact: sometimes when you pass by the Nightclub Attendant, he says "Kifflom" which is a word used by the Epsilon members to greet each other.
Requirements
The only general requirement in order to be able to unlock the Epsilon Outfit is a Nightlcub. You either need to own one or head over to your friends' Nightclub. After you have unlocked this Outfit, it will be accessible through any one of your wardrobes.
