I’d love to play princess with Twilight’s coronation gown too. <3

Relatable! HAHAHAHA!

Someday, Starlight. Someday.

I like to think she’s doing this because she looks up to Twilight. She wants to be just like her.😊

Having one of these moments.  

I like that expression on Starlight’s face.
 
Also, one might say she was caught with her pants down, if there were evidence that she was wearing pants.

@Spiritus Arcane  
I don’t think she’s worn that particular dress since before she got bigger.

@neo4812  
Actually Twilight’s body type is noticeably bigger since she became an alicorn.

@Spiritus Arcane  
there all basically have the same body model

Surprised it fits.

This is why starlight is best unicorn(celestia is best alicorn, thorax is best bug king, chryssi is best bug queen❤, soarin and thunderlane are tied for best pegasus, gallus is best griffon, and so on…)
