The content you show are accessories for Character Creator.
CrazyTalk 8 is compatible with content from Character Creator but as CT8 is now quite an old product it is only compatible with characters and content from Character Creator 2. It isn't compatible with content from Character Creator 3 unfortunately.
So the way it would work is you would create your character in CC2, add clothing, hair and accessories as required and then export as an .iAvatar file. Now in CrazyTalk 8 Pipeline you could import the .iAvatar file where you can then save the character, clothing, hair and accessories into your CT8 library for later use.
Please Note: You need to have CrazyTalk 8 Pipeline version to be able to import and export content.
