Thanks everyone for your replies. I will be in Chennai. Just checking the weather it isn't as hot as i thought it would be - about 35 for the average high all next week. So it shouldn't be a problem for this former Florida girl. :-)
As far as the linen pants, I hadn't really considered how much they might wrinkle. But it's worth thinking about. Also good to know about the skirts as I have quite a few of those that I can wear. (So glad to hear that I don't have to go with pantyhose.)
Maybe the female colleagues in my office are just more cautious about eating out when they're in India. It's good to know that I can head out alone to a restaurant.
Thanks again for all of your advice.
