I can’t say more. Sadly I don’t know what game it is, sorry.
My research team tells me that this is from TERA – The Exiled Realm of Arborea.
I’m presuming that those bits of metal in the high level armor project magic or something, and apparently are so rare to find that that’s about all she could wear. Personally, I’d wear a t-shirt and pants either under or over it, but this is why I’m not a strong female character I guess.
