This minimal western or cowboy shirt has become Raf Simons' signature style since taking over at Calvin Klein. A slow burner, and despite it being seen on the Kardashians, it feels modern yet retro at the same time. It's almost like a space uniform with its flat pockets and details. There are lots of colour combinations and I'm surprised more high-street retailers haven't copied it.
ASOS DESIGN had this homage with contrast pockets and matching yoke for that Calvin feel without the out of this world price tag.
