What does the hierarchy of your accessory look like? If it’s multiple parts, that will explain your issue: accessories will not resize anything to body scales except for the handle part, annoyingly so.
If that isn’t the case, more details are going to have to be provided. Try to think about what you’d want to see in a thread if you were trying to answer someone else’s question. There isn’t much I can do with vague code and no other explanations around.
