Local tips for Seoul
Seoul in December is properly cold and dry — nights regularly drop below freezing. A long padded coat (what locals wear) is worth its bulk.
Thermal base layers make the difference on palace and market days spent outdoors; you can wear lighter clothes on top.
Many restaurants have floor seating — trousers that are comfortable to sit cross-legged in help.
