I have a job interview this week, planning to wear a black pencil dress - not the most fashion forward, I know, but it suits me and looks professional and it's not a particularly exciting or creative role so I'm not worried about dressing a little boring, but what to wear over it??? I don't know if a blazer is a bit too 80s power dressing (plus I have a big chest so depending on the cut a blazer can sometimes make me feel a bit too busty), but then what else? Is a cardigan too casual???
