Fashion in OSTO is primarily obtained through in-game activities and distributed through lore-relevant NPC merchants rather than RNG lockboxes or cash shop systems, making costume collection more straightforward while still requiring targeted currency farming.
Many of these vendors are located off the beaten path, encouraging players to explore the world of Arborea while building their collection.
The three (3) main fashion currencies—**Federation Armory Bills, Ancient Currency, and Modern Currency**—are each tied to different content and vendors, granting access to race-specific, legacy, and newer costume sets.
Federation Armory Bills are one of the three fashion currencies available in OSTO and can be exchanged for a variety of costumes through select NPC vendors (Federation Armorers), each featuring a selection of race-specific “local specialty” outfits.

These race-specific vendors only accept Federation Armory Bills.
