How to pass an input in a function derived from another class?

[Alexa.Ki (Alendromeda.ki)]

EFahionType is declared in the Item base class, and I want to pass it as an input in a function under character base class.
What I am trying is : void ReplaceSkeletalMesh(EFashionType* FashionType, FName Name);

Error is EFashionType is not defined.

void ReplaceSkeletalMesh(EFashionType FashionType, FName Name);
