Custom Website Domain

For a few months now I have been questioning whether or not to buy a website domain. When designing my CV, business card and postcard I found it offputting to put a Wix adress in the contact infomation. Today I decided to purchase a basic plan on Wix which gives me my personal domain (freyacasserly.com). When I saw that my full name was avaliable I thought it made sense to purchase to make my digital portfolio look more professional.
