You're about the same size as me (I'm a bit taller and boobs slightly smaller).
For me, F&F at Tesco are good for trousers. I bought several pairs the past couple of years ( including a 100% linen pair), they're all wide leg which balance out my boobs and they all come down to my shoes. I wear fitted v neck tshirts and vests because i don't need extra material flapping around. My vests came from Zara and have a square neckline, places like George at Asda and (if they have them) Primark do good fitted v neck tshirts. I'm a cardigan person as I get cold so I have loads in various colours that I chuck on in the summer (nothing big or bulky or frumpy just fine knit waist length but keeps me warm).
I also tend to wear ankle grazers to work in the summer with a plain top (i have some Bravissimo lace back vests), then a pair of suede moccasins (I refuse to wear loafers as they remind me of school shoes).
Dresses that are fitted in the body and then go out flatter more than straight down. My absolute favourite is the Charlotte dress by Bravissimo, if you can find it in your size on ebay/Facebook/vinted grab it.
Jeans are a bastard at the moment, Mom/boyfriend/girlfriend styles don't suit my shape and make my arse and belly look huge (from the crotch down I look okay) and I hate barrel leg. I'm currently wearing mid rise flared from Superdry. They don't envelope the belly like others which I find just accentuates my belly.
Try looking on Vinted and Ebay for Pepperberry/Bravissimo clothes if you want something more dressy. If you find something in Super Duper Curvy (they did do a few styles in that size) it would fit better than Super Curvy.
I feel your pain with bra shopping, it's one of the things I loathe.
