As an offshoot from another thread, I'm starting this one. A poster on these forums stated that these women in the below picture "look like professional interpreters" Quoting that poster: For the most part, I agree with this poster. I would like to add that in my industry, there is some leeway for interpreters to wear "smocks" which are simply solid-colored jackets worn over their normal clothes. Depending on if the interpreter is a full time interpreter or if they're a part time interpreter, that will affect their attire. I've worked with certified interpreters who are hired as admin assistants as their "day job" at the office. They are allowed to dress business casual, and as creative admin assistants tend to do, they dress creatively, often seasonally. Off the top of my head, I remember blue/black striped sweaters, white shawls, orange turtlenecks, white/navy plaid blouses, and green cardigans. When an interpreter is needed, the certified admin assistant are called to do so with a smock if necessary. If their interpreting skills are needed in advance, they are informed and are expected to show up dressed appropriately. I have seen them dress like the picture above with advance notice especially if someone like a company executive or a customer will be present, vs. a conference call where they're not seen and have to dress to impress.
