Ariana Grande and Billie Eilish Wear Matching "Office Siren" Suits, But Couldn't Look More Different

Aesthetics-wise, it doesn't get more different than Ariana Grande and Billie Eilish. The latter is an rigid tomboy (save for the occasional Met Gala slay), who loves oversized streetwear and baggy suiting. The former, meanwhile, is as feminine as they come, wearing girlish gowns in pastel hues, inspired by her Wicked character, Glinda the Good Witch.

It's for that reason fans were shocked when the two appeared on stage together, wearing basically the same outfit. On Feb. 4, the pop stars sat down for a Q&A about Grande's film Wicked, which is set to release its second installment at the end of 2025. Grande went uncharacteristically professional, abandoning her fairy princess persona for a boxy suit that easily could have been plucked from Eilish's famously androgynous closet.

The "Eternal Sunshine" singer wore a charcoal gray Saint Laurent blazer with exaggerated shoulder pads and matching wide-legged trousers. Stylist Mimi Cuttrell helped her layer the corpcore staples over a white button-down and maroon neck tie, for a take on the office siren aesthetic.

Eilish, on the other hand, was dressed in her typical fashion—that is, in baggy clothing from the boy's department. She put her own spin on the classic look, wearing a striped dress shirt and vintage maroon neck tie under a loose-fitting varsity jacket.

The star then added a bit of her signature casual flare, via light-wash jeans that puddled around her ankles. Though she too was wearing a suit, Eilish's rumpled outfit was the antithesis of Grande's crisp co-ords.

Their footwear, meanwhile, was also in opposition. Grande went for black pointed-toe pumps, while Eilish finished her look with polished loafers. Both shoe choices—and their outfits, overall—spoke directly to each of the women's personal style. Bottom line? They're birds of a feather, even if they're not identical.
