Pick Out Your Outfit in Advance — and 4 Other Rules the World's Most Stylish Women Swear By

Take stock of your wardrobe while paying attention to the pieces that are worn the most and the pieces that still have the tags on. Are there big gaps in your closet? Essentials you're missing or need to be refreshed, like the jeans you've worn to death or the little black dress you keep telling yourself to buy but keep forgetting? Make a list of the items you need to buy or replace while removing the pieces you haven't worn and placing them in piles for donation or consignment. Just the act of taking inventory will give you a more concrete idea of what your style looks like and what areas you need to invest in (or maybe stop buying) for a more complete wardrobe.
