I dunno about the new look. It seems more formal than her other one which is nice. That one struck be as a little too travelly -- 'just attach a skirt to her travelling gear, should be good to go'. I was hoping for a little more white.
That's strange. If anything, to me it seems like something she'd wear when she doesn't need to appear courtly or... elegant, I guess. Something more informal, especially compared to her proper dress. I kind of agree with @ajiehb - it hits some "hedge witch" aesthetic, even if she doesn't really look like Morrigan to me.
And now that I look at it... feathers? Harpies! It's all coming together, dammit!
