Aviary Keeper at the Costume Store

I think the Aviary Keeper should be quite simple. 
B has asked me to use the set as influence for this character and keep him textual and so he would be "at home" in the set.

We've agreed to keep him very basic, a white shirt, black trousers, black shoes and a rustic waistcoat. He hasn't yet been cast, though she has someone in mind. Today I went to the costume store to see what they had in terms of waistcoats and this is the one I've chosen. It's a very rough fabric and looks very worn down. I'm hoping that it will fit as this is the best option that we have!
