exotic: (adjective)
1.
of foreign origin or character; not native; introduced from abroad, butnot fully naturalized or acclimatized
So yeah, use of this word is proper. Exotic as for abroad, not knowing the language, culture etc of country whence main character in PrimeMoverAndShakers' story origin, as oppose to woman of colour (what a long, dull term, languages tend to reduce and shorten long phrases, so I hope something appropriate will come out soon), who lives in same place, or at least have knowledge of that place.
