Below is a sample women’s clothing list. (All items link to Amazon.com for your convenience).
City wear/everyday wear: In Mumbai and Delhi, Western dress is perfectly acceptable. You’ll see as many Indian women wearing jeans and t-shirts as saris. The case for covering up is the same, though – it’s best not to wear clothes that are tight or revealing. Go for light, comfortable clothing.
Temple Wear: Covering up is not just recommended here – it’s essential. Many temples have a dress code, and won’t allow you entry unless your head AND shoulders are covered. In 2016, Madras actually enforced a ban on all western clothing in temples, refusing entry to anyone wearing jeans, shorts, skirts, short sleeves or tight leggings.
Your best bet is a long, loose skirt (calf or ankle length) and a plain, long-sleeved top or shirt. If you don’t have long sleeves, a long scarf draped over your shoulders should be fine. Wear shoes that can be easily removed, as you’ll be leaving them at the door anyway.
If you want to be really respectful, then a Kameez top or a full Sari will be the best received. This is what Lyric (my wife) wears when in India.
Going Out: The same applies: cover up. India’s cultural and tourism minister issued a statement last year imploring foreign female tourists to refrain from ‘skimpy’ clothes, particularly short skirts and dresses. It’s actually a matter of personal safety.
