Ponytails are incredibly versatile. Your ponytail's placement can dramatically affect your look.  High ponytails sit on the crown of your head so that the ponytail is visible from the front. These are very dramatic and fashionable.  Tying your hair just a few inches lower gives a more sporty look. Low ponytails at the nape of your neck can make you look down-to-earth. Another less common type of ponytail is 1 tied to the side of the head instead of the back. Side ponytails can make you seem quirky and fun.
