So I'm a bit stuck, I can't find the starting outfit they gave me in my wardrobe, but it won't let me do anything until I do. It says the section I'm supposed to go to, but even in the section I can't find it...?

In the wardrobe theres four main sections.

The starting outfit is the newbies adventuring outfit right?

First go the inventory and click ont he item. Then use it.
Then...
Go to items, click on outfits, then press the right arros to the right of all the boxes until you see and item that has a white ebackground instead of a grey one.
