An outfit can make you extremely self conscious or boost your self confidence. Choose pieces that accentuate your best features, hide your flaws, and fit you well.  For example, if you have a tiny waist, wear shirts, sweaters, and dresses that are cinched at the waist. If you want to mask your midsection, wear a peplum skirt, shirt, or dress. If you aren’t comfortable rocking a crop top or a backless dress, don’t wear it. Makeup is designed to subtly enhance your natural features, not mask them.  Experiment with various products to discover the makeup application process that best suits your features. Remember, too much makeup isn't attractive. Try to highlight what is attractive with makeup instead of using too much. Sometimes, girls look better without makeup.  Create a flawless complexion by covering any blemishes you may have with foundation and then concealer. Enhance your eyes with natural shades of eyeshadow. For a dramatic look, line your eyes with eyeliner and coat your lashes with mascara. Give your cheeks a natural glow with blush, bronzer, and highlighter. Complete your look with the perfect shade of lipgloss or lipstick for your skintone. Little details, such as manicured fingernails and a radiant complexion, can attract the attention of boys. Set aside time to care for your skin and nails.  Cleanse, moisturize, and exfoliate your skin. Protect your skin with sunscreen. Trim, shape, and if desired, paint your nails. When your wear perfume, scent, eau de toilette, body spray, scented lotion, etc, boys will remember your scent and associate it with you. Prior to going out, spray a small amount on your hair. When you encounter a boy you are attracted to, flip your hair to subtly waft the scent in his direction. Boys and girls are more attracted to people that smile than to people that frown. Smiling also has the added benefits of making you and those around you feel happier. Laughing is also very attractive. It illuminates your face.
