Provide the option to mark purchased items on a Favorites list. When wearing an item add a star icon along the upper right to add/remove the outfit on the Favorites list. If an umbrella is used the star is for the umbrella. Faded Star is not on the list and bright, focuses Star is on the list.
The Favorite category would be added to the drop down window beneath "Umbrellas." Items in the Favorites list get a Star icon to signify they are in the list when viewed from other categories.
