In The Sims 4 High School Years, the new Trendi Fashion feature was introduced, but only a limited number of CAS pieces can be used when creating a fashion look. This mod expands Trendi to generate a list of all CAS items you own (based on the packs you have installed). IMPORTANT NOTE: The list generates at 6am each day, so after installing the mod you must wait until after 6am either the current or next day for the list to generate with all items.
To install, unzip into Sims 4 mod folder.
