I bought all the required items and put them into my wardrobe. However the achievement does not account for them for some reason. Could anyone give me some advice on how to complete it?

Is the achievement still not working for you?

Did you check the achievement page/click on the tab for Sight For Sore Eyes achievement? Also, you could try clearing your cache. The wardrobe achievements seem to take a few minutes to register, so don't worry if they don't show up right away. (Unless it is taking far too long--like over an hour--then I would file a ticket.)

Thank you for your feedback, Min. It indeed took a while for the achievement page to register the items as present in my wardrobe. After I saw they were marked as present I returned to my wardrobe. The achievement popped up after going to the 'organize items' tab in my wardrobe.

I consider this solved :3 thank you~
