Favorite clothes/costumes

The show has lots of really great dresses, outfits, and costumes for our characters. I’m curious to know what your favorite outfit or costume for our ponies is? (You can include comics.)
 
Mine is:
 

 
RD may not be my favorite pony but I thought her Gala costume was absolutely splendid and matches her so well it’s ridiculous.

 
Also this, because it’s adorable.

 
also
 

 
because cute.

AJ and Twilight’s coronation outfit. Finally, she gets to wear her hat.
 
Don’t know if that’s because Rarity had such little time to put it all together or because she didn’t care…

Dash’s gala outfit and Beatnik Rarity.

I second Beatnik Rarity.
 
Add Drill Sergeant Spitfire to that list.
