This is at least unusual; in fact, it’s almost Blanchettian.
But the slightly blousy abdominal region (due to the dropped waist) is giving this thing a really weird line, and I don’t love how the neck cowl plays with that. Why not just have it come up higher and close around the actual neck? And raise that band to her actual natural waist, which would enhance her natural shape rather than warping it. I don’t know. I DO appreciate that she’s making interesting choices; I just think this one desolates her smaug.
