If you're sick of digging through piles of clothes and trying on ten outfits each morning, maybe it's time to take stock of your wardrobe. Forgetting that you have things, unworn items with tags still hanging from months ago, and re-buying things are all signs that you need a wardrobe overhaul.
If you're ready to "go minimal," try this method: look at your life and what you where when. Then do the math to make sure you have no more clothes than you would need for two weeks, in any season. This means that even if you can;t do laundry for a few weeks, you're still covered, but the laundry pile doesn't overflow with a month's worth of clothes.
For example, say you work in an office five days a week, go to the gym three days a week, and like to garden on your weekends. With this system, you would have no more than ten pairs of work pants, ten work shirts, ten suits, etc. for each season. You would have no more than six sets of gym clothes for each season. You would have no more than four grungy gardening/housework outfits, and you would have no more than 14 t-shirts and 14 sweaters.
If you can live with less, great!
If you're really ambitious, try using layers in basic colors to skip the seasonal shift altogether. Try wearing black pants, jeans, and khakis that can transition easily between seasons. Cardigans, blazers, and light jackets also work well.
Some exceptions include dresses, tuxedos, and costumes for special occasions. But be honest with yourself! Will you wear it again, and will it fit?
