Dressing for September
Late summer into early fall. Hot afternoons, cooler mornings — bring a layer.


September moves from late summer into early autumn. Afternoons stay hot while mornings and evenings turn cool, and by Chuseok there's a real autumn feel. Lingering heat and a returning daily swing arrive together.
A tee with a thin shirt or cardigan — off when it's hot, on when it's cool — works well. As the month goes on, single-long-sleeve days grow more common, so shift the balance toward autumn with cotton pants and slacks.

Frequently asked
Can I switch to long sleeves in September?
From late month, single-long-sleeve days increase. In the hot early weeks, a tee plus a light layer is better.
How do I handle September's swing?
Hot by day, cool morning and evening. One easy-off light layer bridges the gap.
What's good for a Chuseok outing?
An easy long sleeve and cotton pants with a light layer. On still-hot days, a tee under a shirt works too.
