We’re off to Singapore and Vietnam in a month- I’d really like a couple of dresses in natural fibres that are at least semi-fitted. I have a couple that are very cool and comfortable but might as well be striped sacks: I’m an hourglass shape and short so something that at least comes in a bit at the waist is a lot more flattering on me. But it’ll be really hot and humid so I don’t want anything tight or heavy. Can anyone help?
