However, the ASX was unwilling to detail the dress code or elaborate on how it is enforced with a spokesperson claiming the organization didn't comment on internal policy.

First Data Corp. network implementations Senior Manager Craig Douglas said there has to be a degree of sensibility when it comes to dress standards in the workplace.

"Our IT staff are expected to look smart or business casual. We certainly don't expect people turning up in grunge jeans or torn t-shirts," Douglas said.

"This dress code has been in place for years and there are some exceptions. For example, its okay to wear jeans and t-shirt during a major install."
