It's the standard outfit. You can see it around here and there. There's a salarian in the used ship shop on the Citadel, as well as Marab in Saronis Applications on the Citadel, too. It's what I would assume to be the more casual between it and the armour. I may do an armoured version, too, but I haven't decided on that. The armour worn by the Shadow Brokers agents looks quite good, so I might.
Oh .. I see. Well I must confess that I haven't paid that much attention to anything that isn't turian so far ... I definitely will do so from now on, I'm set to replay the games soon anyway so I have them in reasonably fresh memory for the release of the final game.
