Citigroup tells bankers to stop wearing jeans and flip-flops

Dressed for success is just not the title of a Roxette song, it's a call for professionalism.

However, staff at Citigroup’s Hong Kong offices have recently needed a reminder of that, according to Business Insider.

The publication has revealed a document issued by the US bank. The document includes a presentation which was sent to the Asian office in November. The document details the do's and don'ts of dressing for the office.

The document was sent ahead of an office move for some workers, according to a person familiar with the matter, Business Insider reported.
