Business dress code mostly consists of smart, comfortable clothing. A lightweight suit is appropriate and ties are not compulsory, except in traditional sectors such as banking or law. Women are advised to wear a trouser suit rather than a skirt. Keep in mind that India has a diverse and seasonal climate, so it is not always hot. Delhi and other parts of north India can be extremely cold in winter. Hotels and offices can also have very cold air conditioning, so it is well worth packing a sweater, or of course a pashmina.
