Because it is a Korean version, the clothes will be wider. You should wear a tight style for your lower body. You shouldn't wear a belt and a pendulum.
If yours is as short as the picture, you can wear a one-step skirt. )
If it's not too short, it looks better with pants. Minipants will look good with Korean tops. Very slim.
Don't wear loose clothes under the Korean coat. Be sure to slim down your clothes, or they will look like maternity clothes.
White is a good match. I suggest you choose ordinary pants, the highlight is to break through the scarf. Wear fashion.
