@Cantonet, that's a gorgeous shirt, are those birds on it?
I understand what you mean about UK summer dresses in our weather! Didn't you live in Hong Kong at some point? The linen dress looks great for UK. I can imagine something like that becoming drenched in the humidity in Asia.
I now have 3 linen dresses, the longer one on the right I bought early last summer and wore it loads, it's quite thin, really cooling in hot weather and very casual. The other two were bought last Autumn and this Spring so I'm waiting to wear them for the first time.
The two on the left are the kind of thing that feel too nice to wear for everyday occasions, but I don't really do the kind of thing that requires dressing up very often. So if I was going to play the 'wear something I don't often wear' game, I'd like to take the opportunity to wear one of those dresses, just because I like them.
I do have a friend's birthday party coming up next month, but what to wear will very much depend on the weather.
