Ah so pleased you found some nice things! I have a lovely dress from Simply Be.
We are very similar height and size. I'm an hourglass but like you, have always had a belly, which got worse with DCs and a C-section.
I've just bought a big, A-line type skirt from Kemi Telford. Not sure if it will be the most flattering thing on me as my legs are one of my better features and it's not very form fitting on the legs. But it's soooooo pretty and I love the designer.
I wear straight leg jeans. I don't own anything else, (except an ancient pair of skinnies which I keep only for the depths of winter when I need to wear long boots over jeans to keep out the cold and damp). I've tried bootcut jeans again recently, but they really make my tummy look awful. Great on the legs and bum, but it doesn't make up for the ghastly belly to crotch region 
. I'm a 16/18 and I have one pair of 16 jeans and another pair of 18s. The 18s are to wear with things where my tummy shows a bit. They're a bit big on the legs, but I turn them up and they look a bit like gf / bf jeans.
I also wear a lot of midi wrap dresses and midi shirt dresses with tie belts. Despite me liking my legs, I rarely wear short skirts as, being on the taller side, it doesn't look good on me, except sometimes with opaque tights.
Sometimes I buy big floaty shirt dresses or t-shirt dresses and add a belt, which also looks good I think.
