The sharp lines of a blazer lift you immediately – they’re so sophisticated and refined. I lived in them all through college, though I could only afford men’s charity-shop suits. Now, I always have a blazer nearby – it’s like my comfort blanket. My confidence is linked to how I feel about myself, my health, my mind, and if an item of clothing can push you into a good state of mind, then that is great. Nothing does that for me more than a great blazer.
