6. Less is not always more.
I know, I know, I just told you, "Less is more." And for some things it is. But less is not always more, sweetheart. When dressing yourself, be stylish, be comfortable, be yourself, (be sexy even when you're of age) but leave something to the imagination. If you're showing off your legs, be more covered up on top. If you're wearing a top that has a fabulous neckline or really highlights your shoulders, be more conservative with your choice of bottoms.
Clothes should fit well. The size on the tag doesn't matter. Avoid clothes that are too tight, they will just make you look bigger. There are ways to highlight your assets with clothes that don't involve showing every inch of skin possible. You will be more attractive and more respected, to both men and women, if you follow these rules.
