The company I work for, dress formal, at least the people that present to clients and/or  have meetings dress formal. At first I thought I should dress formal or at least business casual and I did for a while, until I notice someone not dress formal. So I started to dress pretty casual and my supervisor said it was okay. We understand you’re an artist and you should express your style as you want. I dress as want but I would never come in wearing a hoodie or sweats that would take it too far. I don’t really think anyone cares how I dress, because there so many employees they see that I’m just an intern.
