Once everything is out in the open, begin to separate your wardrobe into categories – clothing, shoes, accessories, lingerie. As you do this, create a space for the items that you plan to donate or discard. You'll have to be ruthless and think to yourself "have I worn this item in the last 2 months?" If the answer is no, it might be time to say goodbye. If it's a weather-dependent item like a ski jacket or a bikini, set it to one side.
Now it’s time to take each category and separate them into different occasions like workwear, at home clothing & sleepwear, occasion dressing, casual social outings, gym wear.
