Olivia Pierson Stuns in Sleek All-Black Look During 24-Hour Vegas Birthday Bash

Olivia Pierson gave Instagram a front-row seat to her luxe Las Vegas birthday getaway on Tuesday, February 24.

The reality TV personality and entrepreneur, 36, documented “24 hours in Vegas for Nat’s birthday 🎂,” sharing a series of polished snaps from the Wynn Resort & Casino alongside longtime friend Natalie Halcro, 38.

In one photo, Pierson sat at a candlelit restaurant table holding a cocktail, embracing refined evening glamour in a coordinated black ensemble. Her fitted zip-front top featured structured white cuffs and was paired with a high-waisted, floor-length skirt that created a sleek, elongated silhouette. She accessorized with black-framed glasses and a structured shoulder bag, while her platinum hair was styled straight and parted down the middle. Her makeup leaned into soft glam, complete with a neutral lip and defined eyes.

Another image showed Pierson and Halcro seated outdoors beneath blue-and-white umbrellas, raising their glasses for a celebratory toast beside a charcuterie spread. Halcro kept her look casual in jeans and a beige sweater, offering a relaxed contrast to Pierson’s monochrome eveningwear.

A final snap captured Pierson posing on a balcony overlooking a serene water feature, one hand resting on the railing as dusk settled in the background.

The post reflected a quick but fashionable birthday getaway, with Pierson balancing elevated dinner style and laid-back daytime moments during the 24-hour celebration.
