Dress one notch more formal than the role's everyday dress code, never less.
A blazer, even for casual workplaces
Even at a famously casual company, a blazer signals you took the interview seriously. You can always remove it once you sense the room; you can't conjure one if you arrive without.
A shirt in a calm, solid colour
Bold patterns can distract from what you're saying. A solid, well-fitted shirt keeps the visual focus on your face and your answers, exactly where you want it during an interview.
Trousers that have already been tailored
This is not the day to wear something straight off the rack and untouched. A quick hem or waist adjustment beforehand makes the difference between looking like you own the outfit and looking like you borrowed it.
Clean, conservative shoes
Scuffed or overly casual shoes undercut an otherwise sharp outfit fast. A simple clean pair in good condition is one of the cheapest ways to look more prepared than you might feel.
Minimal, deliberate accessories
One watch, one simple ring, nothing that jingles or distracts. Interviews reward calm, controlled impressions, and pared-back accessories support that without you having to say a word.
