Take a good, hard look at the items in your dresser and closet. Marie Kondo recommends taking everything from your dresser and closet and making one big pile to go through all at once.
Ask yourself: What do you wear regularly? What sparks joy? If you truly love an item, keep it. But if you're saving a certain piece of clothing for an indeterminate occasion, say goodbye.
When you've gone through everything — and discarded quite a bit — it's time to properly fold what you're keeping. The KonMari method dictates folding shirts and pants into small squares and then storing them vertically in a drawer or shelf. That way, you can see every single possession — and nothing gets squished at the bottom of a pile.
