What clothes do you need to bring to travel to Korea in June?

As far as the weather in Seoul is concerned, it generally fluctuates around 10-25. It is estimated that short sleeves will be worn in June, so it is good to bring a thin knitted coat. After all, it will be cold there sooner or later, and the air conditioning in the mall is also cold. My friend just came back from Korea last week. He wears short sleeves all week in Korea, but he doesn't wear a thin coat. He will wear it for a while when he goes shopping at night. I hope it works for you.
