First, plaid shirt with jeans, if it is spring and autumn, you can also wear a white bottoming shirt.
For a 23-year-old boy, at the age when he just started working, if he wants to leave a good first impression on others, the overall clothing collocation should be gentle and not too frivolous. This pair of jeans and plaid shirt is definitely a classic in sven collocation, and it is also more in line with the temperament of boys of this age. Jeans show the youthful atmosphere of boys, and plaid shirts make the external image of boys more gentle.
Second, black slacks with a sky blue shirt, and then a suit jacket. This kind of clothing collocation belongs to a more professional style. For young men who have just entered the workplace, this kind of collocation is definitely more in line with their temperament, and it also allows boys to have a transitional stage.
The reason why we don't use white shirts with black slacks here is that we don't want boys of this age to suddenly enter a special business stage. Sky-blue shirts can make the overall clothing collocation easier.
Thirdly, if you want to go out to play, then I suggest that boys wear retro slim jeans and then casually wear a white shirt with a strong sense of design.
This kind of collocation is simple, at the same time, it can make boys' temperament more calm and mature, which is also good for boys around 23 years old.
