Before talking about the specific collocation, let's make a note: the fabric of the shirt can be solid color, striped, or checkered. These patterns can be hidden or visible, the lines can be thick or thin, but generally white is more or less dominant. I take a dark blue or gray (as shown in Figure 1 and Figure 2) solid color suit as an example to illustrate the general rule of matching with a solid color top, then there are three patterns for shirts for you to choose from : Solid-colored shirts, striped shirts, and checkered shirts, the first two options are obvious at a glance. According to the British vision of classics, the checkered seems to be not so formal, so it is not particularly ideal to match as a work wear or urban style. Therefore, we give priority to matching with solid color and striped shirts. As for which kind of stripes, fine Stripes, rod stripes, and multi-composite stripe patterns are all possible.
