Shower regularly, east well, exercise, dress like you care, (but don't go over-board) but most importantly... do it for YOU. It shows when you're trying to look good for other people versus trying to look good to feel good. All of those girls going out with fake everything and $500 shoes are too concerned what other people are thinking about them, and that's not attractive.
Truly self confidence is the most attractive thing. Be happy about yourself and others will see it! Just not overly lol Also wearing your hair down, or other things that embrace your natural beauty. Everyone has it!
You don't have to have the perfect freaking body or $200 clothes to find love. If someone truly loves you, they'd love you if you gain a little weight, and they'd love you if you didn't have designer clothes. You just need to be yourself and only yourself, just remember that a original is always worth more so don't be someone your not. :)
Do yoga everyday. Half an hour is enough. But make sure concentrate on it, make every minute of the half hour count. That's for external beauty. Finish a book per month. If it's good, two weeks are enough. Just calculate, for a year, you can read 12-15 books. Only in a few years, what's the amount of knowledge in your mind? Countless. That's for your inner beauty. A woman is attractive either for a hot body or for a wise mind. If you have both, how can you not be charming?
simplicity always is the best...but be physically healthy,eat well,wash,wear light makeup(if you want),clean nails,clean and brushed hair,clean ears,nice cloths(doesn't have to be the most expensive) oh and dress in what you feel the most comfortable.Just remember do what you feel is best and smile:))
