This costume worked ok on stage but I did have to make a few adjustments.  The head piece needed to be fortified with black cardboard, I also had to make adjustments to make it fit better on my forehead.  I needed to wear a slip
so that it had better coverage (thin material) I also added thumb holes so the sleeves would not ride up .
I am 5'5  125lbs it hit me on my ankles, so I needed to wear flats.
