I see two possibilities here… either the creators of the Tara of the Twilight novel were visionaries thinking way beyond their time, or this bikini armor trope is really lazy and uncreative.   But which could it be?

Her long shapely, coltish legs slid into the delicious, warm curve of hips, and her breasts were full, firm, and wonderfully soft. But Tara was raised to be a fighting woman, not some man’s pampered pet and plaything. For she had a War Maid, a virgin swordswoman sworn to the Moon.

Okay, I think I know which one it is.
