In the workplace, even clothing choices matter. Though our era emphasizes fairness and justice, constantly reminding us that "you can't judge a book by its cover," the truth is that the business world is quite pragmatic about dress code and uses it as a marker of professional hierarchy.

I remember working as an intern at a TV station during university. Once, I rushed out the door wearing flip-flops, thinking it would be convenient for riding my scooter in the rain. I was bouncing around the office hallways when a senior colleague scolded me: "Do you think this is your home?" with a look of disdain. At the time, I thought they were being overbearing.

I've also seen fresh graduates, starting in August when the weather is hot, wear shorts with dress shirts thinking it was cool. They didn't realize that workplaces are different from playgrounds. Once in the office, they were called out by their boss: "Are you here to move boxes? Your appearance needs to be professional and presentable, not like a junior assistant! No shorts at work from now on." Many people are shocked by such stern requirements and even resist them. I've even heard of male colleagues getting attention from the CEO for wearing capris.

As I matured, I realized that workplace dress codes reflect your taste and personal style. Your posture and demeanor convey refinement and presence. Even if your abilities haven't caught up yet, your first impression should tell people 'you have substance!'

When in Rome: Different Industries, Different Dress Codes

Of course, different industries require different dress standards. A female engineer friend once shared: "I don't understand why my colleagues dress so elaborately when we just sit at computers all day typing and barely interact with others." Most people stereotype engineers as casual flip-flop-and-shorts types, though this is just a stereotype. In engineering, actually, overly formal dress stands out. That doesn't mean wearing a tank top, but clean, neat attire—a blazer with trousers or a collared POLO shirt—carries casual professionalism and projects efficiency.

Conversely, for executives, managers, or business development staff who regularly meet clients, appearance requires careful attention. As a journalist frequently attending important events like ministerial transitions, product launches, and parliamentary sessions, I wear a dress shirt with a skirt or trousers, heeled shoes, and a blazer. Even in 38-degree heat, I wear long-sleeved jackets because journalists must convey professionalism and substance. Good grooming tells people 'you respect this job' and 'you value your professional identity.'

Also, if your skirt is too short with exposure risk, always wear safety shorts or pants underneath for safety. Reporters are constantly on the move—one gust of wind can lift a skirt unexpectedly. If your photographer colleague notices, it harms your image. Plus, getting in and out of interview vehicles increases exposure risk. Regardless of personal concern, taking protective measures is the smartest way to preserve your reputation.

A junior colleague also shared that she once attended an international trade show, initially planning to wear a floral shirt and jeans. But she realized she represented her company and might attend various seminars or meet clients. A floral shirt felt too vacation-like and lacked gravitas. So she chose a striped, slim-fit outfit instead. She said she was glad she changed because at the venue, exhibitors and speakers were impeccably suited or in formal wear. Had she worn that floral shirt, she wouldn't have dared enter the hall—others might have mistaken her for a junior assistant.

Finally, though appearance is important and you shouldn't come to work looking slovenly, what truly matters in the workplace is your work ability, attitude, politeness, and adaptability. Clothing is just a bonus, not a substitute for results. Developing both internal and external excellence attracts more attention.
