“Happiness is the most attractive accessory a young woman can have.”

     ".... If happiness is the most attractive accessory a young woman can have, then a smile would have to be the most charming cosmetic. Make-up, if applied tastefully and in moderation, can enhance appearance. But no amount of eye shadow, lipstick, or mascara could possibly compete with the natural attractiveness of a genuine smile. It brightens the room. It cheers others. It communicates friendship, love, and optimism so much more than any cosmetic ever could. It puts people at ease and is welcoming. Truly in the world of glamour, there is no close second to a genuine smile...
     "If you are discouraged about your appearance, it will help to see yourself through the eyes of those who love you. Hidden beauty seen by loved ones can become a mirror for self-improvements. This phenomenon of the person internalizing the expectations of others with subsequent positive change has become known as the Pygmalion effect, after the famous play in which the “guttersnipe,” Eliza Dolittle, becomes the refined My Fair Lady. The beauty was always there; Eliza only needed help from others to discover it...
     "It is not the smile alone that is beautiful. Delilah surely smiled at Samson, and Potiphar’s wife at Joseph. These were women of the world whose smiles were devoid of inner beauty. “Tell me what you smile or laugh at, and I’ll tell you who you are.” (Marcel Pagnol, quoted in Reader’s Digest, Sept. 2007, 95)
     "The virtuous smile is truly beautiful as it radiates in a totally natural way. This true beauty can’t be painted on but is a gift of the Spirit. It is literally letting your light shine before men. When virtue is combined with obedience to the Lord’s laws of health and respect for the human body, young people truly become temples in which the Holy Ghost dwells, giving them a beautiful aura. It is this beauty that is most becoming and enduring...
     "The world prizes body-baring “beauty.” Hollywood markets it, advertisers exploit it, and the media promote it. The Lord, however, “seeth not as man seeth; for man looketh on the outward appearance, but the Lord looketh on the heart” (1 Samuel 16:7). The kind of a man a virtuous woman wants to marry also “seeth not” as the natural man seeth. He will be drawn to the true beauty she radiates from a pure and cheerful heart. The same is true for a young woman looking for a virtuous young man.
     "In pageants, there is only one declared the fairest of them all. But with the Lord there is no competition. All have an equal privilege to have His image engraven upon their countenance (see Alma 5:19). There is no truer beauty."
