Poor you Sass. ds2 had me up at 5.30 so it gave me an opportunity to peruse the internet and get some ideas for you. Let me know what you think of these ideas.
Capsule wardrobe = Jacket/blazer, Trench/mac, Overcoat, Parka, Jeans, Smartish trousers, a few flexible dresses, tops/shirts.
Jackets - i find one or 2 smart jackets which go over most things are really handy to smarten up an outfit. Don't go too long tho as with your height the material will swamp you.
I would recommend Reiss for blazers and jackets i think they are classic enough to last but also can be cut sharply and quite on trend.
Tailored
Linen
more linen
I also think trench coats/macs are a must for a capsule wardrobe. With your colouring a classic beige may suit you. But be careful with shape and length. The other thing to watch is if it's double breasted and you are ample of bosom and broad shouldered it can draw attention to that area - if you get a double breasted one i wouldn't do it right up to the top and leave it open to give you a deep v shape drawing the eye down. Or you could find a single breasted trench (which is what i would advise to go for - less material to flap about and more simple looking).
I rate hobbs for coats and trenches so i would keep an eye on their website for sales
Not double breasted
Pale blue (i really love this one but might be too fussy round the boobage)
Lovely but pricey
Jeans
AAAaaahhh i can't find jeans for me so am in no way qualified to help anyone else. If you like skinnies Uniqlo and New Look get good press.
high waisted which is great to hold in a wobbly tummy.
I also very much like the cut on these (especially if you like that jeans, shirt/t-shirt and a blazer look) relaxed skinny or these .
Cigarette pants
Jigsaw black
Dresses
good colour might be too flouncy tho.
dark pink
pink
If you are broad shouldered, big boobed and like pencil skirt silhouette i can not recommend a bentley ruched dress enough. I have 3
Diane Von Furstenberg ones. They are super super flattering and come in a variety of rich colours. I also have 2 bentley ruched tops to wear with skirts and keks. Get a bra with straps wide apart and some control tights for your tum and you will be a sex goddess. i promise.
