"Short hair is all about attitude and confidence," says hairstylist Rodney Cutler, who works with celebrities like Emma Watson. "A woman with short hair comes off as incredibly striking, and it makes her seem liberated and comfortable in her skin." Here, our favorite celebrity crops right now.

"Short cuts tend to look best on oval face shapes. "Emma is one of the lucky ones—her face is very balanced, so she can take risks with her cuts," says Cutler, who gave the actress her pixie. For Watson's look, the right layers make all the difference. "You want something that is round through the top and square along the sides, so it doesn't look boyish," he says. "And make sure they don't trim your bangs too short. Here, we swept the bangs to the side and added some height to the crown, which gives it a little more of an evening feel."

Berry's piecey cut is edgy and feminine. To recreate it, "ask for long, chunky layers at the top and more tailored pieces on the sides and in back," says hairstylist Anh Co Tran. "Be careful not to overtexturize thick hair, because it will become wispy and impossible to style. Chunky layers keep the body and movement."

"This works for her because she needs a bit of hair around her face to balance out her small features without overpowering them," Cutler says. Make sure you tell your stylist to keep the bangs soft and the sides slightly squared off. "It shouldn't be rounded out completely, or it will look like a full-on bowl cut."

Wood's layered crop gives off a definite rock and roll vibe, with softness. "When you have a strong jawline and cheekbones like hers, balance it out with closely cropped sides and dramatic height on top," says Cutler. "Short bangs aren't for everyone, so this is a good style if you want to keep a little length but still want to have a fun, short hairstyle."

"When you have a fuller face, you need a little volume on top to elongate the shape rather than widening it," says Tran. As Williams's cut shows, short bangs help break up the style in the middle of the forehead so it doesn't look too round.

For a full-on rocker look like Goodwin's, ask your stylist to "shave the sides and the back to punk it up a bit," says Tran, who gave her the cut. But don't go too crazy: "The shorter, shaved pieces should stay down at the very bottom, close to your ears and the nape of your neck," he adds. "If your stylist goes too high, it becomes a boy's haircut."

If you're not quite sure you want to commit to supershort hair, this one's for you. "It's kind of like training wheels," says Tran. "Ask for a graduated bob with a strong side part—that will create a little bit of a sweep and add to the dramatic effect." So what makes it such a good beginner's cut? "If you don't like it, you can grow it out without any awkward in-between shapes," he says. "And if you love it, you can keep going for an even shorter cut."

This daring bowl creates a strong silhouette. "You either love it or hate it," says Cutler. "The shape is severe, but it can be very striking." But be careful. Done wrong, it will look "like Jim Carey in Dumb and Dumber," says Tran. Keep it pretty by asking your stylist to start in sections, using the tip of the scissors to keep the cut as soft and rounded as possible, says Tran. "The hair in back and at the nape of your neck should be slightly square with rounded edges."
