And yes, Astoria's influence while everyone is in El Minha is still present, so everything is still translated and understood by everyone in the Circle, and Circle members will have no issues communicating with anyone in El Minha.

The fashion is a bit of an amalgamation of a few different styles. As this is a merchant city, that is no stranger to strange tourists, it's possible to find a bit of anything around the city. In general, though, the natives dress in a fairly desert-fantasy style, with loose linens, patterned garments, layered clothing, etc. They will not look strangely on any type of style, especially because it means you're a tourist, and therefore more likely to spend a bit more coin than a native would on the local fashion.
