Rarity gets turned into a dragon (baby dragon). Now she only trusts Spike and hides from anyone else.
Idea from beirirangu, requested by my awesome followers! :D

This story will have two endings.

On one of her regular hunts for gemstones, Rarity discovers a treasure trove beyond her wildest dreams... and the lavender-scaled dragon who collected it. Despite a rocky first meeting, Rarity and Greenfire soon find themselves drawn to each other more and more. But the question remains: How did a young dragon end up in the Everfree Forest all alone?

An alternate universe story that puts our favorite purple dragon and his beloved fashionista into a slightly different situation. Art used with permission from the wonderful ArtisteFish!

Now with a TV Tropes page! Thanks go out to Poptard and whoever else might feel like editing it.

Wanting the moment to be perfect, she seeks help from Dusk Shine. The only pony, which she’s aware of, who knows about her crush and the two come up a plan to ensure the day goes off without a hitch, Barb will spend the day with Elusive before finally confessing to him at her party at the end of the day.

But sometimes… even the simplest of plans can have a few hitches.

Elusive has rejected Barb which causes her to be convinced that she's actually been Dusk's waifu all along. Now Dusk has half hatred & gratitude for what his friend Elusive has done. Because come-on, every nerd wants a waifu. No not a wife, a waifu. You hear me yah fu?

All ponies of the same race and age are exactly identical -- except for their manestyle, color, and cutie mark. That's why Fluttershy was able to be such a perfect copy of Rainbow Dash during Twilight's magic duel with Trixie.

Spike notices this, and contemplates the possibilities.... including, much to Twilight's chagrin, the possibility of changing her into Rarity for a day.

Can Twilight talk him out of this mad idea? Or is she doomed to spend an afternoon dressing up in classy outfits for Spike? Find out in the first and last chapter of this riveting tale.

The events of this story take place before Twilight Sparkle became an alicorn.

Spike is a dragon with mare troubles, and one of those mares just happens to be his mother. When he meets Lyra, who has troubles of her own, he hatches a plot that they think will be mutually beneficial.
