Interesting. As an aside, do you remember the discussion a while ago (I believe it was Una who started it) because she was curious about how much our loungewear has to reflect our outside-the-home style. I can't recall the thread title. But people seemed to go different ways on that. Una ended up buying a very nifty lounge jacket!!
You know, I am very strongly drawn to many of the piece you own, at least in theory. (Sadly, they don't always look great on me, but that's another story).
What I see in this range of items is a sort of understated drama. On my own thread today someone noted that my aspirational style was artistic but NOT bohemian. I think that's correct, and I think most of these items skew in that direction. Actually, they all do. Apart from the Cacharel shirt, they have a very urban feel, but not UWP. Even the Cacharel shirt feels urban because you'd wear it with a touch of irony; it's a vintage item that you know is vintage.
I liked Rae's comment about architechturla structure; in all cases the cut and drape of the fabric are vital to the garment's effect. They do not draw attention to themselves in an obvious way, but there's a sophistication to them.
Still...I think you already know this about yourself and your preferences. So i don't think I've helped you much here!
