What Seoul is wearing today

Today's street photo is added with the 07:30 KST update.

Morning weather reports for the Sunday warn of a wide day-night gap and showers from the afternoon, and tell people to take an umbrella.
At a morning low near 14 °C, the usual look in Seoul is long sleeves with a thin cardigan or overshirt rather than padding.
Midday reaches about 25 °C, so layers come off: T-shirts and thin long sleeves, with sneakers the default for walking.
Hazy air (fine dust is in the bad band) means a few people wear KF94 masks on the street, especially on public transport.

Trending now: what you'll see locals in

Hooded thin light jackets (SPAO 'Thin Light' hood jackets, Musinsa top 20)
Wave fleece hooded zip-ups (Dimitri Black, Musinsa)
Arc'teryx Atom hoody and jacket in black (Musinsa)
