Get rid of the old and tattered. Give anything too small to the local women's shelter. Buy shoulder pads. Other than a new bra, nothing will bring more life to your current wardrobe than a pair of shoulder pads that help your clothes hang better on your body. Buy a new white t-shirt.
Nothing says drab winter like whites that are now gray and spotted.
Add a crisp white shirt to your wardrobe. Wear it over jeans, with your suit separates or over your favorite bathing suit or khakis. Get your brows waxed. Nothing will open up your face better than a brow waxing. Wear oversize hoop earrings.
