Jester Pinkie was so much fun to watch. Definitely something she'd be good at.
However, when I first saw her in the jester costume, the first thing that went into my head was Pinkie's Cupcakes costume. I guess it was due to the multitude of different colors, stitches and symbols seen some of the garments.
Heh, Originally the mark was going to be a star on my OC to kind of be a joke torwards my OC's name Stargazer. But the size of th ponies eyes as well as the size of the head made it difficult to make it not like this so I decided to change it to what it is now.
It looks great on Pinkie with the rest of her outfit although!
