I don't have all the specifics in mind, because I'm not sure of everything in your closet, but I do have an idea percolating here. How about you try "Smart Casual" for a bit of a spin on things?
Angie's formula for this is: smart jeans + dressy top + jacket + dressy shoes
Here are a couple of her posts on the topic:

Here's the entire 'smart casual' archives (there's not too many to read):

I would love to see that Missoni for Target multi-colour blouse you have paired with smart jeans and dressed-up shoes/accessories. I'm not sure if this blouse would go with your white Paige Hidden Hills jeans (or even if white jeans would be considered smart casual) but I'm liking the idea. Or, alternatively - dark jeans with this blouse, really pretty shoes and a nice blazer. I'm thinking this might make a fabulous date night type of outfit for spring.
Even without a jacket, I have really enjoyed seeing Angie in this formula, and I think you'd look fab in these types of ensembles. You have lots of beautiful blouses, dressy tops and shoes. How about trying 'smart casual' with some of them? This is a little bit new-ish in that it's often easier to do smart casual in winter when you can just tuck jeans into some dressy-ish boots. But, it's spring. That means fabulously dressy flats or heels instead of boots. Soft, dressy blouses.
What do you think?
ETA: I see that Zapotee and I are on the same wavelength
