A dark checked waistcoat creates the inner area between a white shirt and grey-brown jacket here. A dark bow tie and chest accent repeat its colour family. A small pale detail sits on the lapel. A dark patterned cap is held at the side, while the other hand rests near the jacket front. The photograph ends in the lower trouser area without showing a complete shoe combination. It mainly reveals a relationship between a quieter large outer field and a darker inner pattern, rather than confirmed textile quality or manufacturing method.
Use the reference first to decide how dark the inner area should be in your own suit. Try the same waistcoat with a quiet neck accessory and view the whole front from a distance. Add the pocket square afterwards. If the cap interests you, decide separately whether you will actually wear it or mainly enjoy the pattern repetition. Let your arms rest naturally for another view so the held front does not determine the comparison. Shoes and hem need a complete fitting; the cropped picture cannot establish that lower combination for you.
