The culture of Gondor had a grander, more civilized feel to it, when compared to the other human cultures of Middle Earth. But the clothing-style was similar to that of Rohan, minus the celtic knotwork. Think general medieval-style clothing. I especially noticed the prevalence of the colors white, blue and gray. Faramir wore a dark forest green ranger's outfit, which is more akin to the favored colors of Rohan, while his brother Boromir, had a beautiful burgundy-red tunic. Of course, the distinctive symbol of Gondor is the White Tree.
A Gondorian member of the Hike might want to choose if they are a ranger, like Faramir, a warrior, like Boromir, a member of the Guard, as Pippin became, or a common person.
