How to wear jeans to work

GET A BOYFRIEND BLAZER

Before you slip on a pair of weekday jeans, consider your workplace and what is appropriate—if you are a banker or a lawyer, you might be limited to twill trousers even on Casual Friday! But if you work in a more casual profession, try upgrading a sleek pair of jeans with a structured blazer. For a classic look, pair a navy blue jacket (like Emma Stone's number) with dark denim or a bright yellow design (like Emily Van Camp’s) with a lighter or acid-washed pair. Think suit and match light colors with light and dark with dark.

EMBRACE SEQUINS

A bit of shimmer is an instant outfit upgrade. If you're a risk-taker (and your office is fashion-forward), try a bolder sequined piece, like Olivia Palermo's eye-popping blazer. For a more understated look, try a shimmery top a la Carrie Underwood.

THROW ON A CARDIGANPrinted sweaters lend charm to a pair of jeans. Look for crafty details that will dress up denim, like Miley Cyrus's semi-sheer style or Emma Roberts's bold zig-zag print.

BUY A SILK BLOUSE

A sweet silk blouse will give your jeans a feminine feel—look for tops with pretty patterns or intricate necklines. If your workplace is more formal, skip distressed denim and go for a crisp pair of dark-wash jeans like Rose Byrne's and Jessica Biel's.

TRY A LITTLE LEATHER JACKET

A cropped leather jacket gives a jeans-and-a-T-shirt look a luxurious spin. Just skip the heavy motorcycle jacket in favor of a cropped fit, like Pippa Middleton's quilted look and Nicole Richie's simple structured style. Add a feminine touch with accessories like a great pair of heels and a fun bag.

LOOK FOR A CHIC BUTTON-DOWN

A crisp button-down shirt is a no-fail piece for the office. For a streamlined appearance, tuck a light-hued blouse into matching skinny jeans like Zoe Saldana, then take it to the next level with chic booties and bold eyeglasses. Or, if your workplace is more laid-back, try a simpler version, like Taylor Swift, and add a pop of color with burgundy flats.
