If the thought of wearing overalls [1] still conjures up images of your childhood, you haven't seen Olivia Palermo wearing hers yet. The fashion pro [2], who has a way of making everything look more elevated, has a styling trick that's never failed to make the former kiddo-only staple into a polished adult-friendly outfit. As we've kept tabs on her looks, we've noticed one key component all of her overalls ensembles have in common: she never wears them with a t-shirt.

Instead, Olivia treats her overalls the way you might style a pair of your favorite skinny jeans. She doesn't let them dictate the outfit but rather adds pieces that lend a sophisticated vibe, like an off-the-shoulder top and statement necklace for a night out or a trench coat and a white blouse for a day at the office. Even with her most casual overalls, she never just adds a beat-up tank top and flip-flops; she steps it up with a blouse and embroidered slippers. She never lets the overalls become the whole outfit, and that's the key. Read on to see how Olivia's mastered the look, then take a page straight from Miss Palermo's playbook and shop the key pieces to get the look.

Olivia styled her black Paige Denim overalls with a pair of embroidered flats, a chic Dior bag, and a long-sleeved sheer top.

While out in NYC, Olivia gave leather overalls a party-appropriate twist with an off-the-shoulder blouse and pumps, plus an eye-catching statement necklace.

Even off duty, Olivia gave her short pair of overalls an elevated update by adding a white button-down underneath. Instead of sandals or sneakers, she added a pair of pretty slippers to finish them off.

Dressing up leather overalls like a pair of great leather pants, Olivia slipped on a pair of ankle booties, a long-sleeved blouse, and a trench balanced nonchalantly across her shoulders to take the look to the next level.
