I've been thinking about this thread ever since you posted the question and while I can't give a specific answer as it's too much work for my brain these days, I can only repeat the phrase I'm so grateful to Michelle for - I hug my wardrobe.
If I have to come up with something, a few pieces come to mind straight away: red dress, purple dress, leather jacket, tweed jacket, pb blouse, skinnies - they are all post-YLF buys. There are some older pieces too, like my red knitted top, ponte knit LBD, another LBD, high-waisted black pencil skirt, navy dress and black velvet midi skirt, but what matters to me is that all my wardrobe is instantly accessible, there are no hidden-from-me items, everything is in rotation (season appropriate) and best of all - I am really picky with regards what gets the privilege to earn the spot on another hanger. There is no despair and "I have nothing to wear". When I am tired my best relaxation is pairing things down even further - I just listed 3 lovely skirts on ebay!
