Instant holiday capsule wardrobe please

[Bumblebzz]

Hello
I am going on a sun/beach/active(isn) holiday in a couple of weeks and I desperately need to organise some clothes.
It's easier to say what I have (2 pairs of shorts: white and denim, denim skirts and two bikinis, 1 pair navy saltwater sandals) than what I don't have. I got through the UK summer with basically no nice summer clothes because I work full time so I've been in office gear throughout all the heat waves.
I think I need tops/tshirts most urgently, but scoop necks suit me best and I'm not having much luck online. I'd also like a kaftan and a couple of easy to throw on dresses. Plus maybe some that can be dressed up for night I want to avoid polyester etc and I'm a 'summer' in terms of colour (so pale/pastel/cream etc all good, I can't wear yellow based colours or I look ill) and like navy rather than black.
Any tips gratefully received...!
Online is best as I have no time to go to shops before holidays :o
Thanks in advance

Thanks both

Ordered some cotton t shirts in Boden sale (very low stock) and some linen stuff from Wrap (also sale) so fingers crossed!

Next linen pocket dress, I got one after recommendations on here but only been able to wear a couple of times due to rubbish weather.It comes up big so size down, can be dressed up and down. Think a lot of t-shirts aren't cotton because of the increased costs this year. Also got a nice plain t-shirt from oasis earlier this year, doesn't need ironing whoop!

Dishevelled which dress exactly please? I found lots of linen blend and linen online.
I haven't been happy with Next stuff in the past but willing to try again.

Thanks Annebronte I'll look at winser too.

I'm pretty sure the Next one is this dress. It's the one I've seen recommended on other threads. I've tried it on before and it was really comfortable but not smart enough for what I was after at the time. I might look at it again for my holidays.

Thanks DejaVuDieter - clearly popular as sold out in every size!

Boden sale looks good right now, lots of cotton dresses and tops.

I "treated" myself to 3 tshirts from Primark this year, £2.50 a pop. I need my shoulders covered, and they always get stained by sun tan lotion...

I find H&M premium really good quality. The first top is good and you can change the length on it with the gather.
