A dark three-piece in a complete front view shows jacket, waistcoat and trousers with a paler shirt and dark tie. Dark shoes complete the image. Both hands are in the trouser pockets and the legs stand slightly apart. Compared with the black close view, the whole colour distribution down to the floor is visible here. The picture still establishes neither identical fibres across the pieces nor the shape of the waistcoat back.
Use the full outline to choose the number of layers deliberately. Try an actual waistcoat with and without the jacket. Sit and check its transition to the trouser waistband. Stand afterwards with your hands free so pocket posture does not determine the trouser line. Then compare hem and shoes in movement. Perhaps the additional dark area over the shirt is your main preference, making the waistcoat the useful starting point. If you want fewer layers, comparing without it can clarify that. The full front view offers an arrangement idea without predicting the real fit for you.
