Recommendations for classic effortless summer dresses for work and holiday

[SoTiredNeedHoliday]

Just that really I am looking for something that says effortless, and I don't wear dresses often, so it also has to be fairly classic and not a 'trend'.
I'd love some that could be for 'smart casual work' and some for holiday even better if can work for both scenarios
Size 6-8, 5'5
I'm 50 but feel 35

Sorry you haven’t had more replies to this one.

I’d be interested in any recommendations too.

Shirt dresses are always a good idea!

I have some linen dresses from Boden that I have worn for work and am wearing on holiday this week - I think it’s called the Irene dress. Can easily be dressed up or down.

Linen dresses from John Lewis and Seasalt are all good. I find they don't lose their colour and fade.
You're a bit late on the season so it will be what is left but you are petite size so you might be lucky.

thanks @SchnitzelAgain I like this one dress. Too bad New Look don't have many stores to go into these days
