Of the inspiration photos Carla I could see you tweaking those to make them your style. A more fitted merino or long sleeve tee, maybe under a jacket or coat. I think you could also carry off the tucked blousy shirt look well.
I have currently two pairs of wide pants.
The palazzo style are new but I have worn them twice - simple tops, fitted or semi tailored, with a jacket as required. I might tuck, or if not a shorter top for sure. I see them styled with the large chucky sweater semi tucked, but in reality I don't see that working on a more delicate fabric - I think that semi tucking an oversized sweater is a hard thing to do anyway due to the bulk...
The brown trousers are a bit trickier. On me I am best to tuck - they aren't the trousers that make me look slim. They add bulk to my legs. But with a tucked top and a platform sneaker or white sneaker they work - and a jacket definitely helps.
I think this second style would (even longer too) would work on you Carla - with your frame I think it would be very flattering as you have slimmer hips and thighs.
I actually think palazzo pants are easier if you have wider hips as they have something to hang off.
