Forget the jeans you wear on casual Fridays. It’s all about dressing up for work

Sorry, casual Friday. After years of it being acceptable to show up to the office in jeans and a T-shirt, the dress-for-success ethos is finding favor again this fall.

And several Los Angeles-base stylists couldn’t be more excited.

“We’ve had a lack of fashion [in the workplace] for years,” said stylist Heathyr Wolfe, adding that the low-maintenance professional attire of Mark Zuckerberg and billionaire or multimillionaire chief executives has made it almost a standard to show up wearing just about anything.

“People want to be taken seriously in something besides just a boring suit, polo shirt or shapeless outfit,” she said.

Laurie Graham King, a Los Angeles stylist and wardrobe consultant, said she knew the tide was turning when she started getting calls from clients saying they had been chastised for being “too sloppy” at work.

“Companies expect you to represent their brand in a positive manner,” she said. “And how you dress is a big part of putting your best foot forward at work. I advise my younger clients who are just starting their first job to dress for the position they want. If you dress like a college student, no one will take you seriously.”

Brands are offering up career-dressing collections that are fresh and modern, predicated on a tailored structured piece and building creatively around that.

“There are so many new [jacket] shapes with sleeve detail that still feel professional,” said Debra Perlman, president of New York-based brand Tahari ASL.

A jacket with a bell sleeve or embroidery detail paired with a slender pant will look more interesting than a conventional trouser suit. Other pieces that Perlman suggests seeking out are pencil skirts, bouclé jackets, shift dresses with statement sleeves and fit-and-flare dress; both dress styles can work with the jacket. Accessories should include a bag that is spacious but not slouchy, and a shoe that offers a little stature while the wearer is on her feet all day.

Now, here are some ideas to jazz up your too-casual work look.

Cole Haan

Animal prints are a perennial fall favorite. Cole Haan is on top of the trend with this block heel loafer in ocelot-print hair calf. $440, www.colehaan.com
