The following dressing (clothing) suggestions for China tours help you to dress properly in different seasonality and occasions.
Unless you have a need for formal or dressy clothes, jeans, slacks, shorts, shirts, blouses and T-shirts will do fine.
A comfortable pair of walking shoes is a must. You will be doing a great deal of walking both in the rural and urban areas of China.
Bring a swimming suit if you wish to swim. Many hotels have a swimming pool. Sun block, sunglasses and a light hat are also suggested items.
In spring (March to May) and autumn (September to November) you will need a lined jacket, woolen sweater or light coat. In summer (June to August) cool cotton garments are recommended. In winter (December to February) a fleece jacket, sweatshirt, or heavy sweater will probably keep you warm enough in the south, but in the north a heavy woolen coat or down parka is a must.
It is often rainy in late spring and late summer, especially in the southern part of China, so bring some rainwear with you, or you can buy it at your destination.
