Dressing for your environment is more than dressing in work clothes for work and a swimsuit on the beach. Dressing for your environment means that you dress to fit in with the people around you, the culture and expectations.
I mean, we’ve all heard the trope that you should dress for the job that you want. That’s great, on the surface. But in practice, you don’t want to dress more than one level above the job you actually have. If you’re in the mail room, please do not dress like you have a corner office. It’s suspect (and won’t serve the work you need to get done). If you want a job as a creative, and you work in the accounting department, you honestly can’t dress like the graphics crew (or IT) – the most you can do is accessorize and hint.
