I can make a guess that most of the people coming to this post probably thought about female armor pieces first.
For my preferences, I like armors that are made for easier movement but covered the vital part. A bonus if it partly serves as secondary weaponry like a gauntlet.
Or blend in armor...
"hey! there were like, girls back there, doing you know what!."
"Could you, like just act normal."
"Nope, this is felt great after all!."
"I wish this is a dream."
I just usually write the story first then keep the analysis of the character to keep it consistent. I kept an analysis log of the plot and character. Well, I start as the latter I guess.
