Ok, I have this elf girl named Callista, she looks really young mostly because she is super short and always wears a leather jacket that is two sizes too big. Below that she wears just a simple pants - shirt - boots situation, and she also wears lots of jewellery. She is the head of a gang whose headquarters are in an elvish nightclub, so she lives in the apartment above it which is very spars since she hardly ever goes up there except to sleep.
What you have done here is classic world building without the info-dumping. Your character, her job, her living arrangements and her wardrobe are all reflections of the world in which she lives in. You've created a very vivid snapshot of your world and as we follow your character around and see the world as she does more of it will be revealed. That is world-building in its most simple form. If done well it can create a world that is as believable as that found in a game like Skyrim.
