Drawing of my head and sholders

I had a drawing done of me, a few years ago, by someone, and i was wearing a yellow water proof hat, and although i love the image i want to use it but with out the yellow hat and coat, so I'm looking to get the same image done, but with maybe a grey top on and with maybe a black baseball cap on, just so i can use the image if need be, in any situation.

From the image below, i hope you get the idea.
