viva, your comments are very insightful and hit right on the nail (or all the nails) for me. The price is definitely a consideration for me because of my current budget overall for new purchases. While I can afford them, they won't give me the most bang for the buck.
Except, of course, when I consider what Barbara Diane so aptly calls "joy per wear" factor...
viva, I think I might have quite a few items similar to what you've mentioned (though not all--I'm lacking in the jackets department). I even like the cooler-weather styling in the Zara website with pointy-toe boots (I have black ones--not sure if they would work) and long sleeves.
Runcarla, I am indeed concerned about how to style and when/how to wear them. I find white pants tricky in general because of how easily they show stains and scuffs.
The funny thing is... before I stumbled onto these, I had decided that my new pant purchase would be a very sensible pair of J.Crew Factory Addison chino trousers in khaki, for their neutrality and versatility. Not sure what this says about my needs vs my wants...
Shapewise, though, these flares are my favorite shape to wear, so that might be part of the appeal.
