What to wear to a consulting interview and first week
Interview
Business formal is the safe default: a suit, or a blazer with dress trousers or a skirt, in navy, grey or black. For a video case interview, a blazer over a plain shirt reads well on camera.
Your first week
Expect business casual in the office and a step up for client meetings. Plan one sharper outfit for day one and keep a client-ready option you can switch to at short notice.
Every day
Most firms settle on business casual: collared shirts or neat knits, tailored trousers or skirts, and a blazer within reach.
