I have no interest in a capsule wardrobe and that mapping exercise had me flummoxed. However I think this advice is spot on:
There was probably a time in your life when you loved your style. Think back to it because it’s likely to have a fundamental influence on what makes you feel good, even now....Of course our lives, styles and sizes change so the solution... doesn’t often lie in recreating what you were wearing circa 1989 but for me, that confident time impacts my style today.
I sometimes think back to my old favourite outfits and I've even kept a couple - not because I plan to ever wear them again but because, like she says, they remind me of what makes me feel good.
