Classic styles include single-breasted or double-breasted designs. The colors are mostly dark blue, gray or black. The fabric is mainly wool or blended to ensure crispness and comfort. Matched with solid-colored shirts, plain tie and oxford shoes to reflect rigorous style. The tailoring needs to be fit, the shoulder line fits, the sleeve length is moderate, and the trousers are not pleated. Suitable for formal occasions such as meetings and business negotiations, it is the key clothing to enhance professional image. Only by paying attention to details and quality can we demonstrate our workplace style.
