The character creator comes with a number of included wardrobe items, and you can make changes to the available items.

Options such as hairstyles, torsos and legs can be edited by changing the Data Tables in CharacterCreator/WardrobeItems/<Wardrobe Name>

On opening a data table, you can change the names of each item, which mesh or texture it points to, its icon, and which body types it is available for. Keep in mind that meshes may have clipping if you use them on body types they were not designed for.

Ensure that display names are unique, Row Names are not changed once set (as it will invalidate existing characters), and be aware that editing any wardrobe items will change those items on existing characters

Edit the ActiveWardrobe data table to enable and disable wardrobes to choose which ones will appear in the Character Creator.
