Urban Chic is a limited time Event where you can unlock 'Urban Chic' clothing for your Adult Sims.
If you start at the beginning of the Event you will have 6 days to complete it an unlock everything. However it is possible to add time.
To unlock all outfits however you will need to complete the collection a total of 8 times to unlock all of the outfits.
You will need to have already unlocked the Fashion Designer Hobby, if you haven't done that already, then check out the Fashion Designer Hobby page in our guide for all the details.
If you don't have the Fashion Studio already, then you'll need to purchase one from the Promotions r Us store.
Our top tip if you are determined to unlock everything or at least as much as you can is to make sure you have at least four Fashion Studios and utilise Sims to work on these workstations all the time. There is a lot to unlock and really to have any chance of completing this, you'll need to max out your production.
We would recommend setting up the four Fashion studios in one house so it is easier to monitor.
