Why does skin tight, or showing some skin all of a sudden translate to over sexualized? Seriously, have we become a society of puritans? There is a major difference between form fitting, with some skin showing, and over sexualized. Its ironic if you think about it, the original women's movement was to allow women to dress as they want, and NOT be hidden in layers of clothing, only to be replaced with "anything that doesn't hide everything, look frumpy or show the minimum amount of cleavage is oversexualized.
There's nothing wrong with form fitting and showing curves.
However when it comes to armour, I prefer it practical and realistic, over the concept of "I'm a feminist, let me wear whatever I want". Open revealing cleavage = a clear path for a sword, dagger or arrow straight through the chest. That's just silly on the battlefield. There are vital body areas that should be protected. (I'm also speaking as an SCA combat archer...)
Lae'zel's armour covers her chest and torso, but reveals her legs for freedom of movement. That's fine too - and is similar to how ancient Greek/Roman warriors might have been armoured.
Now if we had "casual" clothes to wear at camp (similar to DA:I - casual clothing when at Skyhold, armour when out adventuring), then people should be able to dress their characters however they want.
