Ok, casual pants and jeans can be worn.

Casual pants with gray or something. Cowboys can wear straight tube and narrow leg pants. Black, dark blue, washed and nostalgic can be used. If it's narrow-leg pants, it's not proper to put the trouser feet into the shoes.

You can buy a black down jacket, but if you want to match shoes, don't be too lady. Both lengths are fine. It is recommended to buy short ones, which look energetic. And it's not short, it's inconvenient, and it doesn't show your legs.
