Looks more like a fashion show to me than fighting gear.
(But to be fair, so do some modern entertainment-based depictions of men in fighting clothes, too).
I read that some germanic tribesmen went into battle all-naked in their forest while attacking and it shocked e.g. the Roman soldiers to the core. This seems to have happened. I think there is a similar myth or historic theory about some Celtic tribes too.
However I did not hear it of any women so far. We need to ask: Is this variant of the 'amazon myth' really historically verified or just a 'meme' or entertainment plot?
Remember that modern action "historic" shows like Vikings etc. as well as the fancy pics above give us an almost fantasy and entertaiment-based image.
Actually for quite a few years now it is one where women are most often even better fighters than men. So we have lots of scenes where one woman alone (!) can slaughter an entire batallion of attacking wild warrior men easily by the flick of a wrist. Watch Vikings or Game Of Thrones and any other Hollwood output and you see me confirmed.
However, among historians even the existence of e.g. so-called Viking shieldmaidens is still debated and not clear if it is mere mythology. Still we take it as fact. The picture that is implanted into our minds: All Norsewomen were brutish murderers and killing machines just as their male counterparts? So were all of the Picts, Scythians, Spartans or the mythological Amazons. Really?
Yes, in every ancient cluture some female fighters might have existed and they trained for fighting certainly. But for me it is not so clear if they really went into battle regularly with their men in their hundreds as it is depicted nowadays and we are 'made believe' by a politically correct 'feminist' Hollywood.
Of course, there are and were women fighting in battles when they had to, e.g. in defence when their home settlements were being attacked. Or for freedom against invaders, as nowadays for example it's many of the curageous Kurdish women who are fighting Isis, mostly with machine guns though.
But we need to keep in mind that historic fiction of the superior fighting amazon most probably is and remains ... fiction. A lot of it seems myth to me, the same is true of some male hero myths, too.
History is bunk, as Henry Ford said, so we need to be cautious here and see if most of this kind of "history" we see in Vikings and other shows is still fantasy and myth rather than was actually historically true.
