Shift Up has not made one good costume design poll.
Two of Modernia's designs were shit
Red Hood's poll was rigged internally so that dress slop would win.
Someone at SU thought it would be a great idea for "Red Hood Cosplay" and "Totally Not Copying Marian's Skin" to be genuine options leaving the only somewhat original idea to be the only one people are actually voting for.
(Their popularity polls are also shit - SU just isn't good at making polls)
