Hailey Bieber and Serenay Sarıkaya have just pulled off the clash every stylist dreads, and Saint Laurent's Paris show was the stage. Both women arrived at the Spring/Summer 2027 show in plunging black tuxedo blazers cut to the sternum and finished with razor-thin shades, and the resemblance was close enough to stop the scroll.
Turkish media call it a 'pişti', the card-game term for a perfect match, and the chatter has moved well beyond who wore it best. Was this coincidence in an all-black room, or did Saint Laurent quietly stage a Hailey Bieber moment for Sarıkaya?
Did Hailey Bieber and Serenay Sarıkaya Wear the Same Blazer?
They wore the same idea, and it is very Saint Laurent-coded. The deep-V tuxedo jacket worn over nothing is the house's Le Smoking legacy rebuilt for today, with hard shoulders and a neckline that drops to the sternum. In the photographs, both women wear narrow black sunglasses and are caught in the same harsh, backlit flash that makes every lapel glow.
W Magazine describes Bieber in a plunging blazer at the show, while Onedio describes Sarıkaya's version as a deep-V jacket with wide-leg trousers and thin sunglasses. That wide leg gives hers one long, sweeping line from shoulder to hem. Onedio also notes that she had walked a runway alongside Kendall Jenner the night before, so the switch to sharp black tailoring was a proper change of gear.

Did Serenay Sarıkaya Copy Hailey Bieber?
The theory is easy to see. One report says Sarıkaya's look echoed Bieber's signature aesthetic, from the sleek styling and minimalist silhouette to the polished beauty and effortless attitude, which raised the question of a deliberate Bieber-inspired moment.
Opinion online followed the usual split, with some saying Sarıkaya carried the look better and others accusing her of copying Bieber. That is a roundup rather than a thread of individual posts, so the volume of the argument is hard to judge.

The case for coincidence is stronger. The invitation seemed to steer guests towards an all-black dress code, and the front row obliged, with Zoë Kravitz, Rosé, Amelia Gray and Bieber all in black.
In a room like that, a razor-sharp black blazer is the safest fashion bet, and Saint Laurent front rows lean towards black anyway. Two women reaching for the house's signature jacket on the same night is more likely by chance than by plot.
Who Wore It Better?
Several online comments describe Sarıkaya as relaxed and cool, and Bieber as guarded. A fair few also point out that Bieber is chased by a far larger pack of photographers, and anyone dressing this low in front of that many lenses would adjust their stance. That explains the pose without changing the picture.
Sarıkaya wins this round. Her relaxed, square-on stance lets the blazer's V run uninterrupted, and that is what makes the look. Bieber's version is just as sharply tailored, but the pose is what sets the two apart. In the Hailey Bieber and Serenay Sarıkaya Saint Laurent blazer face-off, the crown goes to Sarıkaya, and on this occasion it is all about the pose.
