The attire really depends on the company that you're applying for. For example, if you're applying to a corporate role, do some research. You will most likely get brownie points for wearing a polished suit/dress with heels. However, showing up with that for an interview at a start up, will most likely give interviewers the impression that you're "stuffy". Before any interview, if you can, always ask HR what the culture is like. My most recent role, I was told that jeans were 100% okay for the interview (maybe not ripped jeans).
Good Luck! 😊 Simone
