Why Guys Love It: Nikki Reed's bun looks simple and elegant yet still touchable. The hair that falls into her face prevents the updo from looking too severe. "Men couldn't care less if your strands are perfectly styled and neat. In fact, he might like you more with some wildness or bedhead, since it shows you're carefree and relaxed," says Fisher.

How to Get It: Make a low side ponytail, leaving a few pieces loose around your face. Twist the length of your ponytail, and wrap it into a figure-eight shape — smoosh it up against your scalp, and tuck the ends into the loop. Insert a few hairpins or tiny barrettes to lock it all in place. Finish with a mist of light-weight hair spray that'll give you extra hold minus any stickiness, like Paul Mitchell Worked Up.
