There wasn't anything particularly feminine about Zam Wesell's outfit other than the shape of the actress's body and that wasn't even proper armor. I really don't see why this has you in such a huff. Why should her gender be so damned important as to put it before other character considerations or the functionality of the armor? If the character isn't one that would specifically highlight her femininity then why should the costume design? There is nothing "drag" about it, and there is nothing about the design of the armor that is specifically masculine. As soon as I saw the first shot of her in the trailer I had a feeling it was a woman and specifically that it was Gwendoline Christie, so if they're going for a big reveal they aren't doing a great job of it.
