Second nightmare night picture! This one is more nightmare nighty. If you missed the first one, you probably have absolutely disgusting tags hidden!
 
I totally swiped this costume from another artist. If you recognize it, well…
 
I wanted to ponify the costume because I thought it’d be cute for sweetie’s teats to be hanging out under the micro skirt. However, I also sketched the analogous costumes from <Artist redacted> for Scootaloo and Apple Bloom. Since I’ll be on a trip for a week, I decided to hammer out Sweetie Belle now instead of wait for everything to be late.
 
I’m not even sure I’ll finish the other two costumes, honestly. They are cute, but not as good as this sweetie one. There’s a textless version because the dialog is really silly.
