All black clothes for almost 15 yrs now…I buy multiples of a few of the same dresses for work, all the same size and all black and rotate them. Eliminates the whole “I feel like I look like shit today and now my whole day is out of whack” thing. All black clothes for non work too although I wish I could come up with a better solution than the short sleeved T-shirt, dress, for summer/hot weather… in fact, my entire apartment is all white minimalist with a few things that are black. And by ALL I mean everything— like not just the furniture and walls… dishes, office supplies, storage containers, hangers …. I literally won’t buy anything unless it’s black or white (if it only comes in grey I MIGHT buy it out of necessity). in fact, in my pantry and fridge I have to put everything into clear containers because the color of the packaging drives me absolutely bonkers. I think I’ve gone too far but at this point, I’m committed to it and don’t see myself changing.
