What’s with Teagan’s outfit in Trespasser?

I know lots of fans are disappointed with Teagan’s looks or attitude towards Wardens in Trespasser, but what bothers and intrigues me more is his outfit?

I think the Orlaisian masks are a bit too much, but what the hell is this he’s wearing? He’s here representing Ferelden to negotiate with the Chantry, Orlais and the Inquisition, everyone’s wearing their best formal attire, and he’s in some beat up armour and dirty clothes (probably smelling like wet dogs too)?

What’s the lore reason for it? Is it to show Ferelden’s aggressiveness on this matter, or is Ferelden so war-torn and economically deprived that they can't afford good clothes now?
