White tee, black trousers and a simple collar jacket

White at the chest and ground gives this limited palette two clear points of light. The black jacket and trousers form the frame between them. With so little decoration, neckline shape and hem position become more noticeable, making the composition a useful starting point for minimalist outfits built from familiar unbranded clothing. Use white heavyweight-style t-shirt to provide a plain center so the larger layers and lower silhouette remain easy to distinguish. Use black straight trousers to keep the lower shape clear so that the neckline, outer hem and footwear can each be read. Use white low-top sneakers to give the trouser or short opening a quiet endpoint without a separate strong color statement. Use black simple-collar jacket to create a compact outer boundary and leaves the lower garment enough uninterrupted length.
