Whistling Do not whistle in public. Be Aware Public displays of affection are considered improper. Indian men may engage in friendly back-patting merely as a sign of friendship. Women may hug each other when they meet, and they may not. Clothing Style You will see beautiful, expensively-dressed women in the major cities.
Men dress rather informally for business, usually without a jacket.
But expensive shirts and ties are becoming more popular as status symbols among business professionals. Dressing Appropriately Northern India is cold in the winter, so warm clothing is required for two to three months. Light and loose-fitting clothing is best in most parts of India due to the heat and humidity during most of the year. In very hot weather, you may omit the jacket. Conservative pant suits or dresses.
