I want to have the style of Nacho Varga from better call Saul

As the title says I want to have this style. I have a few shirts like it and it definitely fits me perfectly. But, I can’t consistently find quality shirts like the ones in the pictures. These were the best pictures I could get. I especially like the short sleeve one and the jacket. I love all the shirts though. I can find pants and shoes all I need is a good source for the shirts.

Thank you to anyone taking the time to help me out!

P.S. if you haven’t seen better call Saul you are missing out.
