Holiday packing: capsule wardrobe time

I'm hopeless at packing for a holiday. First of all I can't do it much ahead of time because the weather where we usually go (Åland Islands in Finland) is always unpredictable, and I have to wait until I have a proper reliable forecast. At least that's what I tell myself, because the real and embarrassing reason is that I can't pack until I feel in the right state of mind to do it.

'You can't base every decision on your emotions,' some wise (or not so wise) friend once told me.

Since we are leaving for our midsummer holiday in two days' time I thougth I'd start the packing with getting a few things in the Net-a-Porter sale. (Where else should one start?). But, I've just been on the phone to them and they say despatch can take up to 72 hours, so I may not get the few crucial items (Marc by Marc Jacobs handbag, Mulberry scarf and Alice by Temperley twill cotton jacket) before we go.

Panic.

Hence, this morning, though I don't feel like packing yet, I forced myself to start the process by laying out the pieces I know I'll want to take. If I could get together a 'capsule wardrobe', I could build on from that.

What do you think - am I on the right track?

Hobbs maxi dress, Castaner black wedges, blue DKNY wrap cardigan (which starred at yesterday's pigeon episode at England's Lane Books), Uniqlo cargo shorts, Citizens of Humanity white jeans, Current/Elliott cropped chinos, Rebecca Minkoff bag. And my Mac, obviously!
