Rarity x Sunburst Gentle but suave fashionista and her anxious submissive nerd husband Iii always think Rarity x nerd is great, she's self assured and smooth and would have no problem leading in a relationship. Sunburst meanwhile is easily flustered, a bit insecure and scruffy, Rares would smooth talk him and groom his wild mane and generally enjoy making him sputter.
Rarity x Trouble Shoes Clyde Clyde is big and clumsy and feels like kind of a monstrous oaf, giving him a small but capable partner just sounds like a great dynamic, rarity both treating him gently but also being hard to startle is nice to imagine. Clyde being scared of f*king up with her but Rarity just continuing to smile kind and giving him some reassuring pets for comfort.
Rarity x Party Favor Iii have a lot of words, most specifically hcing Party as an enby and Rarity very happily helping them explore their feminine side, having fabulous soires and Party helping to prep and decorate Raritys fashion shows.
Rarity x Tempest Shadow Absolute starlet x bodyguard vibes. Rarity is the dom between them, you cannot fight me on this. Kissing "ugly" scars and helping tempest find and carve her crystal horn ? So much good content for them. This ship is criminally underrated.
Rarity x Spitfire Powerful, famous older ladies ? Rarity being hired to help design wonderbolt show suits. Both of them showing up at the red carpet together, being total show stoppers. Great.
Rarity x Frazzle Rock Gem nerd x Gem nerd, Rarity helping Frazzle feel beautiful and seen. Also Frazzle is a mule
Rarity x Daring Do/A K Yearling Shadow Spade and Daring Do clashing, slightly different genres but both powerful leading ladies. Hero and her beautiful spy companion.
Rarity x Limestone Pie(yes I know it says Rarirock not Raristone, ignore) Rarity and her tsundere miner wife. Limestone has NO clue how to deal with being flirted with ? But wow Rarity sure is pretty,,,,
