I wore a vest to the testing center. The lady told me that I couldn't wear a vest because a vest isn't a sweater or light jacket. I am allowed to wear a sweater or light jacket but if I ripped the sleeves off then it's not okay anymore. My brain hurts from the stupidity. A vest is part of indoors attire. Took my test in a white tshirt and was chilly the whole time. The staff also says you can't wear anything that has the same material as a jacket because it could make noise. This is never clarified anywhere.
