Dash and Rarity huh? Honestly, the first thing that comes to mind when I think of the ship is Rarity going “It’s alright darling, I can fix her. She’ll be a proper mare before the night is through!” and I dunno if I like that heh
I honestly don’t think the two are really well suited for each other, so I’m gonna lean towards ‘no’, but nothing leaps out at me as being ‘Wrong’ or a reason to hate it. If you think you can make it work, you’re free to try.
Iwould ship her with this dash
