This is supposed to be Chara from Undertale. (I don't know if you can still recognize though)
At first, I kind of went overboard with designing the costume just to realize I kind of don't recognize the character anymore which I didn't like. So I went for an "aura" approach for Chara lvl99. Although my final piece did become stiffer and busier looking than what I originally planned, I hope that you still like it.
