What to wear in May
The most comfortable stretch. Thin long sleeves or a tee with a light layer.


May is the most comfortable month of the year. No heavy layers, no heat worries — just fabric and silhouette. With plenty of outdoor events, aim for something easy to move in that also covers the cooler evening.
A thin long sleeve or tee with a light shirt or cardigan is plenty. UV starts to strengthen, though, so on bright days a hat or thin long sleeve to shade your skin helps.
Seoul averages 14°C at night and 25°C by day. Twenty-five calls for short sleeves while fourteen still does not, so short sleeves plus something to throw on carries all of May — especially with evening plans outdoors.

What to wear in May, women and men
For women in May, short sleeves or a light shirt with one cardigan covers the whole day. For men, short sleeves or a linen shirt is the baseline — the sun strengthens this month, so pale colours and breathable weaves noticeably lower how warm it feels.
