Dona that's interesting - I far prefer spring and autumn colours to either summer or winter - I suppose there's some instinctive liking for colours that are better on you, and I'm an autumn on the brink of spring.
SE I have considered the batwing Pure t-shirt several times, but I think batwings make me look a bit boxy up top because of my boobs. I like that rust Reiss jacket a lot (if I had spare dosh I would totally order it), but I think it would fill the space in my wardrobe which I have reserved for an oyster coloured tux jacket. I like the silk satin shirt for you, but the breast pockets on this similar one are good on me, so doubtless bad on you. The thickness of my ivory Pure one is pretty good though (although it has breast pockets, so that helps!), so you'd probably be fine with the colour block one. You could get a cheap nude camisole from M&S/H&M (I used to have a great H&M that cost £2.99 and went under all see through things).
I would settle for any handbag I could find at the moment that fit in with my clothing personality and colours. I am still limping on with the £20 River Island one like this, and it is seriously falling apart after only 4 months or so of use. I really bought I'd find something perfect before it completely died...
