There are many kinds of sweaters. Cardigan sweaters and pullovers are generally suitable for men. These two sweaters are a perfect match.
Let's start with cardigans. If cardigan sweater goes with shirt, you only need to wear sweater outside and shirt inside.
Cardigan sweater can be buttoned or unbuttoned, and the top two buttons of the shirt can be unbuttoned, of course, only the top button can be left. These styles are very harmonious and beautiful.
Then there is the pullover, and the collocation of pullovers and shirts is also very classic. Under normal circumstances, white shirts are more suitable for matching pullovers, and sweaters of any color will not feel abrupt.
You can only show the collar of the shirt, which will be more special. You can also expose the collar and cuffs of the shirt to make the style more changeable and give people a different feeling.
