How do men in the workplace wear professional fashion?

Since you want to be formal and trendy, why not take the yuppie route? Formal tops and trendy items are completely consistent with the literal meaning. The first type is a suit with popular items as an inner layer.

The second type is a suit, shirt, and casual fashion pants, not a complete set.

The third type is a suit jacket, jeans and a shirt.

The fourth way is to only keep the suit jacket, and use trendy items to match the inner layer and trousers.

The four forms of yuppie expression are exactly the same trend, but they are different from each other. I found out carefully that the main style item actually only uses two suits, and four different images can appear. If you keep changing the inner outfits on top of these four, and add two inner outfits, there will be eight types. The expression of yuppie.
