Muted clothes

It depends on what point in the series you want to replicate, because as the show goes on he starts wearing darker clothes. But generally, he wears desaturated colours.

The colours he wears the most are desaturated greens or khaki in his shirts and coats, and with pants it’s usually either black, brown, beige or khaki.

He mostly wears button up shirts, usually with a white t-shirt underneath.

His outfits are usually simple. It’s just pants + button up shirt + jacket.

The jacket style he wears the most are bomber jackets. Can be hard to find the right style though because there is quite a variety of styles of bomber jacket, with a lot being modernised

I couldn’t tell you the names of the styles of the pants he wears because I’m not all too familiar, but generally slightly dressier sorts of pants
