I second the Ancient Nord armor. It’s one of my favorites, and I think it suits her. Jensa found hers in a cave somewhere, quest-related. It was kind of a trophy for her. Of course, Aravi may feel differently about her connection with the Companions, specifically with Aela.

I’ve never had a character who wore the glass, but maybe someday. I think it would work for a Redguard warrior. It’s very pretty when it catches the light.
I like Aravi’s barbarian bikini. It gives her free range of motion.

Plus it reminds me of her Cyrodiil look.
Oh, I love fighting dragons in the dark! It’s scarier. Plus the soul looks awesome, like in Aravi’s picture.
