Not only are natural hues like this dark olive among the trending colours in summer 2025, they never go out of style and are therefore considered timeless. This outfit, consisting of a shirt-jacket made from a high-quality fabric with leather-look enhancement, a long-sleeved cotton shirt and pleated trousers made from pure linen, plays with the colour palette’s various gradations. The subtle hues and different surfaces lend a varied and modern touch to this almost mono-coloured look.
