I would ditch the jeans. A sleeker look is almost impossible unless maybe leggings or skinny, which are sadly often tight and restrictive too.
I also think baggier, stiffer mom jeans are hideously restrictive, and maybe we are evolving out of that old denim staple nowadays towards a more sleek, comfortable look?
Jeans are hardy little buggers, and I have bo idea why someone would wear them everyday - but they are popular and we are not all the same, so of course it isn't that important.
I am the same height as you, 8-10 and do suit a sleeker silhouette. It doesn't have to be expensive or austere either. For causal I do suit decent quality leggings with a loose, longer length top or fine knit jumper. These sit softly against the body but don't overwhelm it, which I think trousers and waisted things often do when we are not tall and robust.
I also like a non restrictive skirt, flowing and soft, so a winter weight lined silk would be my dream, with darker tones, coupled with a fine knit cashmere top that flows neatly to my body - nothing chunky. A long squishy cashmere hooded cardigan, like a robe is a nice, luxe addition.
You can locate comfy, contemporary stuff that doesn't bunch or cling but still gives a nice slender silhouette, if that's what you're after. Jeans and a parka are practical, as a many trends, but they often have a blockish look too.
You don't need a waisted dress, perhaps consider a loose but sleek fit jersey one or a neat tunic over tights or leggings. At our height, whilst not exactly petite, a lot of voluminous denims and chunky stuff really overwhelms.
