The Best Haircut Trends for Fall 2012

Proving that short can be tough and sexy, the singer's geometric crop has a square shape that balances an oval face.

The imperfect edges and tousled texture make this cut forgiving on every face type and super easy to maintain.

Take a cue from the fiery redhead's newly debuted bob, which is short in the back and slightly longer in the front to convey just enough edge.

Slicing into the hair to create layers gives movement and shape to thick hair. No wonder Mendes has been loyal to it for years.

It's piece-y and perfectly undone -- the thinly sliced ends are the key to what gives this universally flattering cut its tousled effect.

It's a street style that's as chic as anything, and looks great on hair that's straight or flat-ironed to show off the intentionally uneven lines.

The feathery edges and side-swept styling lend a prettiness to this classic borrowed-from-the-boys crop.

The more untamed this cut is, the better. But the subtle shearing at the middle and ends of strands is what keeps the volume in check.

The flippy layers draw attention to the face while the soft texture -- best achieved on fine to medium hair -- adds a feminine feel.

The combination of straight-across bangs with ultra-long length elevates a simple look into something stunning, and slims a square face.
