Saint Laurent Announcement
Hailey’s pregnancy announcement was a style slam dunk. On May 9, 2024, she set the internet ablaze with a series of jaw-dropping photos and a swoon-worthy video on Instagram, from the couple’s vows renewal ceremony.

Justin’s comment, “Mommy Bieber?????,” was the icing on the cake!
Bump-baring Babymoon in Japan
Instead of getting caught up in nursery planning or newborn shopping, Hailey and Justin spent their final months as a family of two on a chic babymoon in Kyoto, Japan. From sushi dates to visiting art exhibits, Hailey stuck to pregnancy-friendly staples, rocking vintage Levi jeans, sculpted outerwear, and luxe accessories.
For her first look, Hailey Bieber nailed effortless chic in a Jacquemus La Veste Ovalo jacket ($1,485) with wide-leg vintage Levi’s, Jil Sander loafers, a Nili Lotan Louise belt ($295), and Giant Vintage sunglasses.

Still basking in the Japanese sun, Hailey dazzled in a zesty lemon-yellow Miu Miu tee, paired with low-slung black trousers and a coordinating crochet bucket hat. This sunny ensemble highlighted her bump beautifully, proving that even in her final weeks of pregnancy, she could rock vibrant, playful fashion while savouring every moment with her husband Justin.

A Week of Glam: Trip to Rhode!
Hailey Bieber rewrote the maternity fashion rules, and it was all glamour, all week in late June 2024. From sleek bodycon dresses to daring lace catsuits, she did not hold back — and we loved every minute of it! Let’s break down her week of iconic, bump-hugging looks that kept New York City buzzing.
Lace Catsuit Flair
Starting the week strong, Hailey stepped out in a head-turning, lace catsuit by Alessandra Rich. This isn’t your typical maternity ensemble, but when has Hailey ever done “typical”?

Totally embraced in all its glory.
Chic in Camel
Fast forward to her Rhode pop-up event, where Hailey served up business-chic perfection. She opted for a camel-coloured bodycon dress that fit like a glove, showing off her growing bump with elegance and ease. The matching boxy blazer added a cool, androgynous twist to the sleek silhouette. This look was the epitome of minimalist glam — bold, yet understated. Snake-print heels and a tan purse gave the outfit just the right amount of attitude without going over the top. If there’s a way to slay a pop-up event, Hailey just nailed it.
Satin Dream
Later that evening, Hailey switched gears for date night with Justin, going for a romantic, cream-coloured satin gown that was all kinds of dreamy. The gown, with its asymmetrical drape and luxurious sheen, moved like liquid silk as she glided through the streets. Paired with square-toed heels and a chic updo, she radiated pure sophistication. The sleek silhouette of the gown cradled her bump in the most glamorous way possible, turning a simple date night into a red-carpet affair. The glow, the gown — pure magic.

The blend of retro charm with modern accessories created a look that’s equal parts nostalgic and current. It’s casual, yes, but with an undeniable edge.
Bustier Chic Meets Casual Comfort
Balancing her work life with laid-back style, Hailey stepped into her Rhode boss girl routine wearing a strapless bustier top by Source Unknown and the iconic YSL Manhattan bag. It’s a nod to power dressing but with that casual edge she’s so good at. Perfect for going from meetings to a quick coffee run without missing a beat.
Laid-Back Luxe with FILA
