Personalized

Give her a gift that shows that you really took the time and effort to think about the gift by choosing something personalized. A necklace with her name engraved on it, for example, or if you're her boyfriend, consider two dog tags with your name on one and her name on the other. You can design a T-shirt on a Web site (such as CafePress.com); she'll have fun wearing it and showing it off to friends. A stuffed animal with her name embroidered on the neck ribbon is a sweet twist on the same old Valentine's Day stuffed animal.
Experience

Instead of giving her a gift that she'll put on a shelf, what about giving her a gift certificate for an experience instead? She'll have fun and then have the memories as part of the gift. Depending on the personality of the girl, you can try a gift certificate for a manicure or pedicure for her and a friend, a weekend away at a nearby resort, a gift certificate for a formal dress for the next dance (with lunch as part of the shopping excursion) or tickets to a big concert. Consider her personality and the things that she likes to do before choosing one of these experiences for her.
Romantic

If you are a boyfriend looking for the perfect gift for your girlfriend, consider doing something romantic. Even if you don't have a lot of money to spend, you can arrange for a romantic evening for your girlfriend's Valentine's Day present, along with a gift from the heart. You can write a romantic message and burn the edges of the paper to make it look old; place it in a bottle for your girlfriend to find, like a real-life message in a bottle. Or create a Valentine's scavenger hunt for her to find a small piece of jewelry that you've bought for her. Use your imagination, and remember that teenage girls love something that shows that you put a little thought and effort into their gifts.
