In my headcannon, Twylight is the last of the Gen 4 Mane ones to return in Gen 5. And she goes through which the Fourteenth Doctor and though; the PTSD from the suffering and blaming herself because her sins such as the Lesson Zero Incident, the Marer Do Well and Walking Dead hoaxes, the division between Rainbow and Rarity involving the swamp, using the cheerleaders on Rainbow, doubting and betraying Pinkie, presiding Capper and Dyscord as well as Tricks and Zecora, supporting the colonists of Appleloosa, playing Fluttershy, scaring Flurry, doubting and betraying the CMC, hurting Spike in the owl incdent, and trying to rob Novo cause dark events and helped many including Opaline to destroy…And caused many wars and deaths. And Midnight Sparkle of her world came from her darkness, nearly conquering all reality. But Sunny heals her. And she stays with them, teaching Sunny as Celestia did for her. And she often wears this outfit only with an ascot tie of paisley and an ikat scarf.

This outfit Fits her more than the 10th Doctor’s clothing. Waistcoats are smarter than blazers and tartan is grander than pinstripe. It rock if the tie was paisley and it she wore an ikat scarf.
