I won't be clutching this thread with Hemming's many shortcomings as a costume designer, but will instead focus on some aspects of the Themyscirian armor I do find interesting...
While I do think that Hyppolita's and Menalippe's costumes are overdesigned and do appear too advanced and SF-like (Wilkinson did a much better job at making Diana's costume appear more grounded - modern in craft, but belonging to an ancient civilization in design), I do like the armor of common soldiers and I do like the fact that they have their own thing going on and are rather unique, instead of being purely Grecian in style (though they do retain some of its elements). Basically, I find them to be a middle ground between Pre-New 52, very ancient Greece inspired Amazons and New 52, more crude and primitive ones.
Pre-New 52:
New 52:
DCEU:
Now, what DCEU Amazons wear does retain some Grecian elements such as bronze body contouring armor and leather skirt called pteruges, but the way the leather bodice and metal upper chest armor combine is rather unique, especially when it comes to those half-pieces that create an aesthetic that is clearly a nod to the myth of Amazons being one-breasted. The pteruges as well have more of a unique look, being in a shape that truly does look like feather (pteruges actually means "feathers") and being quite long, which is something I'm not very fond of as it's rather impractical. But this is always the case with movie armors, I'll get to that more later...
Jenkins herself has said next:
"Themyscira is influenced by the Greek but it’s clearly more then that. It’s a place that has the ‘you’ve never been to’ kind of feel. To me, they shouldn’t be dressed in armor like men, it should be different. It should be authentic and real – and appealing to women.”
And I do kinda get the impression that it is an armor designed by women for women with the aesthetic they went with.
What I do find especially interesting is the recurring eagle or bird theme with those outfits - Diana (in her WW outfit, I believe her regular one as seen above is that of a new recruit or a student) and Hippolyta both have eagle crests on their armors, Antiope has an eagle on her shield and a studded leather skirt in the shape of a bird's tale and Menalippe and aforementioned common soldiers have these long, feather-shaped pteruges that create something of a bird's tale aesthetic as well.
As for the practicality, armors are not entirely practical, but that's Hollywood for you... it's expected. To be honest, even the way Diana carries her sword on the back is completely impractical and was not how swords were truly carried historically (there's a reason why such way of carrying a sword is called "Hollywood style") - idea has always been to be able to draw the sword as quickly as possible, while immediately getting into defensive position... by carrying the sword sheathed on the back, it doesn't just take more time to draw it if the sudden attack happens, but one would completely expose him/herself for the arrows or melee attacks that way. Longswords were carried like a soldier would carry a rifle, over ones shoulder. Anyway, I digress...
I already mentioned the length of those pteruges, which by the way don't really offer that much of a protection (they are pretty much useless against direct attack) and are, similarly to Roman cingulum, being primarily there for aesthetic reasons and the sake of modesty (of course, cingulum was also a badge of rank in the Roman army).
High heels (or more correctly - wedges) are probably the most impractical thing, though I do believe they are meant to add more height to the actors, so I'm willing to give it a pass... they probably won't be seen much in the film and they do wear flat footwear as well.
As for the probably most ridiculous thing in fiction ever - the notorious breast armor, yeah, it is as impractical as one would assume. Armor is meant to deflect a weapon, so there shouldn't really be any dents and cavities, as it makes it easier for the tip of a sword or a spear to penetrate the armor there... such dent between breasts would mean that it makes it easier for the enemy to go straight for the heart. However, one and only thing that redeems this to an extent is the fact that the aesthetic is being Grecian-inspired, making it a female version of the male ancient Greek muscle cuirass that historically did exist:
I probably bored to death any unfortunate soul that courageously embarked in tackling this wall of text, but these are some things I took from the Themyscirian design we saw so far, which I found to be interesting (not expecting anyone else to share my sentiment). Anyway, to make a long story short (way too late!), there is an interesting concept behind these outfits that I like and that for most part does end up looking good. Despite Hemming being involved.
