Design based on this  
I hope Cuddlehooves doesn’t mind - I mean, it isn’t copied or anything, but the similarity can be seen  
(if you are Cuddlehooves, hi! Is this okay?)
 
For a thing that took less than a week to make I think it turned out pretty okay. I’ve only finished it yesterday, but so far so good - after all I sewed it myself for me to wear, so it fits me pretty well, yay!
 
Though, I’m not entirely satisfied with the collar and sleeves (I could have made them longer)  
The bottom part is a bit oversized by design
