I had my model over today and had a size fitting I chose this model because I believe he is around the right size and also he is athletic very close to the look I'm after.
We tried the shorts on first I the fit was nice. The only adjustment I will be making is to tapper the legs.
The shirt and waistcoat I see the same problem with shoulders the model has pronounced traps which make his shoulders sloppy, I will need to pick up the shoulder ends to clean up the front. once I fix
I find the trouser's need the most work waist band needs to be dropped and tapered a little bit more. I had to fold up the bottoms as they are more than an inch too long.
