I'm still tweaking the bird's beak on the hood, but the body of the costume is done, thanks to the big, big help of my wonderful husband.
The shirt is actually 2 layers: one long-sleeved shirt with a zippered neck covered by a sleeveless spandex workout top. I embroidered the raven crest on there. We have yet to see consistent pictures of Raven's costume, so I just created an "idealized" version of the breastplate. I created a paper template and transferred it to the spandex top with tailor's chalk. And that was harder than it sounds! Then I embroidered it with a simple backstitch in a metallic thread. Again, spandex and metallic thread are very difficult to work together!
Here's a back view.
And a front view (ignore my hair, it was being naughty).
And a view of the hood, the beak is folded under because it, too, was being naughty.
