Is a denim jacket appropriate with running shoes?

First of all, I think it is okay to wear a dark denim jacket with sports pants and sneakers.

Both boys and girls can wear it.

For example, I randomly searched for a few pictures on the Internet for reference.

Let’s talk about boys first:

The first one is a denim shirt, but it would also be good to change it to a thicker denim jacket. Such a good-looking set is not necessary, and the shoes can also be replaced with more sporty ones.

It looks like this, but I think these pants have a bit of texture. . . . , or I can think of something with a better texture, it should be pretty good.

It would be a good idea to replace these pants with sweatpants of a similar color.

Girls:

It’s really hard to find the matching picture I want. The effect after matching with sweatpants is about this. In the picture below, I didn’t choose the base layer well.

The above can be used by the subject to see how these items look when paired together. If I were to choose, I would be more inclined to like the combination of boys in the first picture.

Of course. If the denim jacket mentioned in the question is purple

the pants are purple
