Plate Armor ---> Hypersexual Bridal Dress

Thinking about 'Pure Heroine Energy,' I have a thought: Why not take that trope and twist it around? What's something every pure girl dreams of, which is usually considered a sign of purity? A wedding dress! Now, what if I just throw an adjective that completely contradicts that in front and see what happens?

Looking at the Prompt, the natural choice to replace is 'Plate Armor.' With a puff, it transitions into 'Hypersexual Bridal Dress.'

The corridor widens and the red carpet grows finer and fancier. The lanterns on the walls are too far away to see if they're still here at all, and the ceiling grows higher - supported by massive columns - presumably to suit the occasion.

Arma's braid slides up her neck, with a nice shoulder-length cascade of hair spooling loose into wavy curls. Glittering ear-rings make their way to her ears as her tiara gains a pink gem and heart motif. Her greaves disappear. Her gauntlets and bracers and so forth turn into delicate gloves that reach up her biceps. Her armor turns white and thin, then spool down to the ground as a beautiful wedding dress in a massive 'flumph.'

For a moment, Arma looks like the happiest girl in the world.

Then the skirt of her dress shoots up until it only barely covers more than her previous skirt did, leaving her legs and ass almost entirely exposed. The back of her dress unties itself and falls down her back before knitting itself together again under her shoulder-blades: It leaves behind a gap that completely fails to cover the small of her back. Her gloves disappear entirely. The hearts and gems of her tiara grow slightly crooked and warped. A thin silver band traces its way around her neck, and another around her hips.

The sparkle and light in Arma's eyes dims and darkens. She continues smiling pleasantly as ever, but it seems a little hollow. Clearly, this isn't the dress of her dreams. Likely, the groom isn't exactly ideal either. I almost feel bad. Almost.

But not enough to keep me from asking: What else can I do with this?
