It's going on my birthday list, HappyGirl :)
I'm recc'ing this left right and centre at the mo - so much nicer IRL and doesn't crease. Looks great slightly tucked into jeans, black 7/8 trousers, and chino shorts (looks weirdly good with an electric blue pair I have):

I'm a fan of harem trousers for warm hols - they travel well, are comfy, and can be dressed up or down. Also a fan of a long jersey maxi skirt and a jersey blazer (not necessarily work together) - the latter can smarten things up nicely without being too workish.
Shoes-wise I am unashamedly wedded to my Birkenstocks bit always take a flat metallic pair (New Look FTW!) and a much-beloved pair of gladiators from Clarks that just look like understated browniah fairly strapping flat sandals, but are actually ridiculously comfy and have more in common with walking sandals, I bought two pairs but they don't seen to do them anymore. Actually M&S has some gorgeous flat leather closed-toe/caged-toe sandals at the mo in tan or black - they were literally like walking on air.
I read a tip on Cup of Jo that might work for some people - only pack in one colour combo for a short holiday - all blues, with white accessories, or just monochrome with an accent colour, for example. I mainly do navy, khaki, cream and grey (or a variation on this) but actually it's harder on hols as so much "holiday stuff" is in brighter colours. Actually that's a good tip - try to avoid buying "holiday stuff" in overly bright colours - the chicest-looking people when you're on holiday always seem to be the ones who look at home there, in normal outfits rather than holiday hear! That totally contradicts my rec for the M&S pink and orange top, sorry.
