Issue With Importing Hats in Blender

I’m trying to import hats onto a rig in Blender however they never appear where I would like them to go and after watching multiple tutorials, which did not help fix my issue, they had hats appearing directly onto their rig.

Here is a video of my issue:

I’ve watched many videos and looked on the DevForum however have been unable to find a solution to my issue.

I also tried moving the accessories to my rig however I was not able to align them correctly. Please help!
