I am being interviewed for a civil service type job, in the environmental field. Is a suit with matching jacket and trousers, blouse, and high heels, too 'officey"? The alternative is some wide leg grey sort of large check 'slouch' trousers and a mustard jumper. I usually wear this with a leather jacket which I realise is a no. I have a black suit jacket, would that work? With heeled black boots? I am overthinking? I do think that you project a lot by what you wear, and that getting this right is important.
