How do I obtain the Epsilon outfit in GTA Online?

To obtain the Epsilon outfit in GTA Online, one must first complete the single-player campaign's Epsilon Program side missions, which are available to Michael in Grand Theft Auto V. Upon completing these tasks, players unlock the Epsilon robes for purchase. To then transfer the attire to the online mode, players should save an outfit slot for it in the single-player game. After doing so, one can switch to GTA Online, where the special Epsilon robes will be available for purchase at any clothing store under Outfits: Designer. It is important to remember that these tasks and subsequent rewards require dedication and completion of a specific set of objectives within the single-player experience before accessing them in the online counterpart.
