Simpson's suit consisted of a modified cotton boilersuit. Typical driver suits are one-piece overalls, similar in appearance to a boilersuit. The word "boilersuit" may also refer to disposable garments such as DuPont's Tyvek suits. The boilersuit may have local names at individual universities. The suit came packed in a small box and was put on like a boilersuit. Unlike coveralls generally, the student boilersuit isn't used for work, but mostly for parties.
