“unconvincing armor” tag
 
YOU’RE TELLIN’ ME. I COULD NICK THOSE THIN ASF CHAIN STRAPS AND BOOM! YOU’RE NUDE AND UNPROTECTED! SLASH OR SMASH!

You’d think Rarity would prefer more armor to better protect her perfect form.

Sexy Warrior Rarity

from the source:  
When I’m sick and under the weather I’ll sometimes have rather odd, unusual, one-off dreams. This week while recovering from my bout of crud I had a dream one evening which was set in a fantasy, sword and sorcerer, Heavy Metal, anthropomorphic, MLP setting. In that dream Rarity was the leader of a flight of mercenary dragon riders that served Princess Celestia. Riding a much larger and grownup Spike she and her forces patrolled the borders and mountains of Equestria.
 
The rest of the Mane Six along other characters from the show and my household or Petina, Carousel, and Sky Brush were in it as well.
