A "closet staple" is a wardrobe essential that every person should have in their closet. These are items that can be worn time and again, and never go out of style. They are versatile pieces that can be mixed and matched with other clothes to create different looks, making them an important part of any well-curated wardrobe. Closet staples include classic items such as a white button-down shirt, little black dress, blue jeans, and blazer or jacket. They are the building blocks of fashion that can be relied upon to create polished and put together outfits for any occasion.
