Essentials

If you only pack a few things, pack these.

Medium-weight coat (wool blend or structured jacket)Essential
Seoul's October evenings drop to 50°F near the Han River and Bukhansan trails — a wool-blend coat or structured jacket is the autumn standard in fashion-conscious Gangnam and Garosu-gil.
Knit sweaters or thermal long-sleeves (2–3)Essential
The 16°F gap between Seoul's October high and low is well-managed by a layering system of t-shirt base, knit mid-layer, and coat — one or two warm knit sweaters cover evening visits to the palaces.
Slim trousers or dark jeansEssential
October's mild temperatures and lower humidity make standard denim comfortable for all-day Seoul sightseeing — slim dark jeans work for Insadong market browsing to upscale Gangnam restaurant dinners.
Ankle boots (leather or suede)Essential
Seoul's October fashion culture peaks with autumn collections in Hongdae and Garosu-gil — leather or suede ankle boots fit the season's aesthetic while providing practical support on Bukchon Hanok Village's cobblestones.
Light-to-medium scarfEssential
Seoul's 50°F October evenings along the Han River and outside Gyeongbokgung Palace create a pleasant chill that a stylish wool or cotton scarf addresses effectively without adding coat bulk.

Light thermal base layer (late October)Recommended
Late October evenings in Seoul near Bukhansan and the Han River start to feel like early winter — a lightweight thermal base layer added under the knit extends your cold-weather range significantly.

Footwear

Ankle boots (leather or suede)Essential
Seoul's October fashion culture peaks with autumn collections in Hongdae and Garosu-gil — leather or suede ankle boots fit the season's aesthetic while providing practical support on Bukchon Hanok Village's cobblestones.
Trail runners or hiking shoesRecommended
Bukhansan's peak autumn foliage draws hikers throughout October — dry granite trails and exceptional views from the Baegundae summit require grip-soled trail shoes or light hiking boots.
Waterproof spray for suede footwearRecommended
October's 7 rain days in Seoul can damage unprotected suede ankle boots and loafers — a waterproof spray treatment (available at every Daiso and outdoor shop in Myeongdong) protects autumn footwear investments.

Accessories

Light-to-medium scarfEssential
Seoul's 50°F October evenings along the Han River and outside Gyeongbokgung Palace create a pleasant chill that a stylish wool or cotton scarf addresses effectively without adding coat bulk.
Compact umbrellaRecommended
About 7 October rain days in Seoul bring brief autumn showers near Myeongdong and Insadong — a compact umbrella handles the season's light and intermittent rain without requiring a full rain jacket.
Light gloves (late October)Optional
Late October mornings in Seoul near Bukhansan trailheads can drop below 50°F before sunrise — a lightweight pair of gloves is useful for early morning hikes chasing the autumn foliage peak.
