Character mis-en-scene

I have not fully decided who I’m going to cast yet. But I have a friend who knows lots of people in theater and will help me find people to cast. But I only need to find three people to be in it. I am going to film on an iPhone. The costume design is going to be a white shirt and black jeans for the main character boy. And then for the psychologist, a business casual outfit that gives off a professional look I will show pictures below of inspo. 

I think this business look looks really well for Delilah and I want to keep it very similar to this image

This image is the closest I can find to my idea for him, but I want to make it look more wrinkly and not as put together but this exact style but almost like he just threw it on and he’s not actually trying.

The idea for the wolf is to have a boy dressed in black jeans and a black shirt but with this mask on so it is obvious there’s a human behind it but it’s dressed as a wolf it is supposed to look like a costume and not exactly like a wolf.
