We all have a couple of outfits that are our "go to" outfits when we need to feel confident. When I'm going to an event such as a conference or interview where I need to impress, I can always depend on my black jacket (above) worn with trousers which are "of the moment" - as in cropped trousers today - and either metallic boots in winter or sandals or edgy flats in summer.
The jacket is a MaxMara but was an amazing bargain. I was rummaging in the House of Fraser department store in Swindon a few years ago when, on the sale rail, I found this divine jacket. And it was reduced to £10!
