Supposedly this is the most-viewed video on YouTube, so you may have already seen it, but if not then let it serve as a reminder that physical beauty is not as important as we often think. The passage below is directed specifically at women, but I think the principles of modesty and spirituality apply to both genders.
1 Peter 3:3-4
Your beauty should not come from outward adornment, such as braided hair and the wearing of gold jewelry and fine clothes. Instead, it should be that of your inner self, the unfading beauty of a gentle and quiet spirit, which is of great worth in God's sight.
