A cosmetics case is a necessity for almost all women. If you don't like to wear a lot of makeup, you can simply keep a mirror, lip balm, a sunscreen stick, face wipes and other basics in your cosmetics case. However, if you prefer to wear makeup on a regular basis, you will want these essentials and more in your cosmetics case. If you don't want to overcrowd your cosmetics case with too much makeup, you can always look for sample sizes at your favorite makeup counter, or you can purchase the purse sizes or travel sizes, helping you to lighten your load.
