A black combination with a dark shirt creates an almost continuous upper area here. Tie and jacket remain dark too. A small chain at the chest pocket and a round lapel detail add pale accents, with a watch at the wrist. The image stops before the shoes and partly crops the head. It therefore shows colour relationship and accessory distribution rather than the complete silhouette or a confirmed material.
If you like the dark continuity, begin with an actual shirt under your chosen jacket. Compare the tie and small details one at a time afterwards. Decide whether you want to distinguish the neck line more clearly or keep it quiet deliberately. The photographed chain is not a necessary part of a dark suit. Check its position seated if using a similar accessory. Add a full-length view with your shoes before deciding on the complete effect. A strong upper crop can easily conceal unresolved trouser and hem questions. A deliberate comparison keeps both areas in view.
