Aurora: The advent and popularity of these flashy pieces of (non)armor have set my mind to wonder: Why do people wear such armor? What sort of protection does it afford? Do the protected members contain regenerative qualities that will aid the rest of the body after it has been hacked to bits? What odd sports do these folk engage in that armored undergarments would aid them? Plagued for months by such questions, I at last found the answer to my question, as well as finding the maker and seller of such finery — Boom's Garden of Waterdeep.

Durkon: "Tha's na leather armor! Leather armor be stiff an' boiled to deflect blows."

Merchant: "Of course, men's leather armor. Women's leather armor amounts to any attractive outfit that has one or more leather items in it. I once sold one winsome young lass a leather headband that was more effective than plate."

"(Indecent Invulnerability) - Bikinis render the wearer invulnerable to any form of damage."

Chuck: "It's lingerie!"

Marcus: "It's +1 to AC and +2 to Charisma!"

Chuck: "It's ridiculous!"

Because I've got my armor, which is really rather silly, on

(It's cut so low I feel like I'm the topless tow'rs of Ilion,

And isn't any use against attackers sagittarian).

I am the very model of a heroine barbarian!

slowbeef: Yes, her "battlesuit".

Diabetus: Yes. Of course.

slowbeef: If anyone fires lasers at [her] breasts or vagina, it's fine.
