This spring, we’ve done the style legwork for him. Inspired by the runway and red carpet, we’ve picked the must-have haircuts and clothes your other half needs. Just hand these pages to him, and we’ll take it from there.

HAIR

The side part isn’t only for your grandfather; just check out the updated take on Ewan McGregor. “It’s not meant to look too perfect,” says Regis Artistic Director Terry Varty. The key is the unfussy blended cut, which is anchored by the longest hair, at the forehead. For an effortless, swept-back finish that doesn’t look shiny and over-gelled, push your hair back along either side of your natural part and hold with a dab of American Crew Grooming Cream ($18.09, Regis Salons).

CLOTHES

Classic four- and six-button double-breasted blazers have roared back onto runways. Proper fit is crucial, or you’ll end up looking boxy. A good tailor will make sure that the jacket has the correct narrow shoulder-to-waist fit.

HAIR

The antigravity, grown-out look has been popular for a while, but Ryan Kwanten sports a fresh, piece-y version. Your stylist will leave a quarter inch of hair around the ears and then texturize the top with a razor or by point-cutting with scissors. “You want a sawtooth effect,” Varty says. To provide fullness and make sure it stays put, work a bit of Regis DESIGNLINE Interrupt Texturizing Clay ($12.69, Regis Salons) through towel-dried hair, away from your face.

CLOTHES

To add some rakish charm to your look, shelve the skinny tie and try a bow tie instead. As shown here, it’s best to keep the rest of your look understated and sleek and let the bow tie steal the show.

HAIR

Exhibit A for why guys shouldn’t be limited to short hair: Brad Pitt, who always looks as if he’s strolled onto the red carpet straight from the beach. Shorter layers near the face are crucial so shoulder-length hair doesn’t weigh you down. Styling is as easy as it looks. A quick spritz of Redken Wax Blast 10 ($10.50, Regis Salons) will give a rougher finish. Then, Varty says, “run your fingers through your hair, pull it back and let it fall where it falls.”

CLOTHES

Be bold! Believe it or not, neon green, tangerine orange, mustard yellow and more are colors you can pull off. If you’re shy, skip the full suit and pick one piece (think a button-down) to punch up your look.

EDITOR’S TIPS

01: What do the handsome fellas featured here have in common? A little scruff. Don’t feel obligated to go clean shaven 24/7. As long as your stubble is groomed, it works.

02: A woman can tell a lot about a man’s character from his shoes. That’s reason enough to invest in alternatives to sneakers. Classic lace-ups with a round toe in black or brown are all you need for a big event. (And keep them polished, please.)

03: You should smell like a million bucks. Skip the drugstore body spray and try a grown-up fragrance. We like Kiehl’s Essence Oil in Musk, $26, Kiehls.com.
