I'm going to Vietnam in a couple of weeks' time.
I've not been somewhere like that for ages; it will be very hot and humid.
I'm pretty fat (about a 20), not very tall and only wear flats and don't do toe posts.
I have cotton dresses and thin Bermuda type walking shorts. Have bought some new cotton knickers, I like microfibre but I think they'll be too hot.
Any tips for comfortable but vaguely stylish clothes?
