Hailey Bieber recently stepped out in a stunning Saint Laurent gown, and all eyes were on her. Dressed in a gorgeous deep mauve color, she truly looked like modern royalty. The outfit gave off serious prom queen energy — elegant, bold, and effortlessly cool.
Fashion is in Her DNA
Hailey Bieber started her career as a model and has always had a natural flair for fashion. Whether it’s a red carpet appearance or a casual day out, she knows how to make a statement. And at this particular event, she did just that. Wearing a show-stopping Saint Laurent gown, Hailey turned heads and reminded everyone why she’s a fashion icon.
Hailey Bieber’s Mauve Dress

The gown she wore was a deep mauve shade — rich and romantic. It featured ruched fabric that hugged her figure beautifully. The top part of the dress had a criss-cross halter neckline with cut-out detailing around the waist, which added a modern, edgy vibe. The style gave off a bit of a “bandage dress” feel, with a flattering, body-hugging fit.
The criss-cross design continued down to her upper thighs before the dress flared out into a flowing, pleated skirt. The train of the dress lightly followed behind her, adding a touch of drama and elegance to the whole look.
Simple Accessories, Big Impact
Hailey kept her accessories minimal, which let the dress shine even more. She skipped a necklace and instead let the sweetheart neckline do all the talking. A few sparkly rings and matching mauve nails completed the look. Her shiny manicure matched the dress perfectly, tying everything together with a classy touch.
Her makeup was soft and glowing — a lightly contoured face, a natural blush, and a glossy pink lip. Her lashes had just the right amount of mascara, giving her a fresh, effortless look. Her hair was left loose and styled simply, adding to the overall graceful vibe.
A Fitting Tribute to Saint Laurent

Hailey has always been a fan of Saint Laurent and often includes their pieces in her wardrobe. In fact, she even wore a Saint Laurent bridal dress when she renewed her vows with Justin Bieber. So, it was a sweet and stylish choice for her to wear the brand again, especially since she was there to present an award to Anthony Vaccarello, the creative director of the fashion house.
By wearing one of his stunning designs, she honored his work in the best way — by wearing it with confidence and grace.
Hailey Bieber absolutely nailed her look for the event. From the rich color of the dress to the elegant design and her flawless styling, everything about her appearance screamed prom queen meets high fashion. It’s clear she knows how to own a red carpet moment, and this was no exception.
