When Jahleel Weaver, Rihanna‘s stylist and LVMH deputy creative director at Fenty House, first learned the multi-hyphenate mogul was pregnant, he was overjoyed. “I was extremely happy for her, knowing how important family is to her and that she always wanted to have a family,” he told Vogue in a phone interview last week. Weaver’s next feeling? “Sheer panic,” he said, bluntly. “What does this mean? How are we gonna do this?”

Rihanna’s calendar of events unspooled in his mind; for a time, in early pregnancy, the star wasn’t ready for the world to know, tasking Weaver with disguising her changing body. Very quickly, however, Weaver adopted what would become a radically optimistic philosophy on her maternity style. Instead of approaching Rihanna’s pregnancy as an obstacle, Weaver declared: “The bump is now the focal point. This is her main attribute at the moment, and let’s just highlight it as best as possible.”

The ensuing looks amounted to one-woman pregnancy fashion revolution—a rarely-seen, unbridled celebration of the pregnant form, with bejeweled necklaces, crop tops, and low-slung jeans that were decidedly not dedicated maternity wear. “I’ve never once looked at anything maternity,” Weaver emphatically stated, recalling a moment in January when a tailor suggested inserting elastic into one of Rihanna’s garments. “She was like, ‘No. I don’t want elastic anything. Ever.’” Weaver agreed: “It’s not very sexy, and it kind of dumbs everything down a notch,” he explained. “You want to not feel as if you’re giving up quite yet, you know?” (In lieu of elastic, Weaver noted, there is “tons” of tailoring.)

Weaver never set out to make a sociopolitical statement: “I didn’t think it was so unseen to see a woman with her belly out,” he said, but once the awed feedback began to pour in, Weaver endeavored to be even bolder with Rihanna’s style. “It’s been, probably, the most fun we’ve had with fashion, ever, in my time working with her.” Here, Weaver shares his favorites of Rihanna’s pregnancy looks—and the stories behind them.

Rihanna’s first major red carpet moment since announcing her pregnancy set the tone: The ombré color and sparkle felt like “such a fresh way to start how we’re going to approach this,” Weaver said. Even before she was pregnant, Rihanna planned to wear the sequined fringe top and pants from The Attico to a Fenty Beauty Universe event in February. Weaver’s L.A. tailor-made “magic” tweaking the pieces to fit Rihanna’s belly: The fringe “just cascaded across in the most perfect way.” After growing up in the 90s and 2000s, Weaver says both he and Rihanna “can’t help but be drawn to things that evoke that era. It was everything that we loved in one look.

“She looked like a mermaid,” Weaver said of the custom Coperni crop top and maxi skirt Rihanna wore to Fenty Beauty’s ULTA launch, a standout for its unique silhouette. Weaver and his assistant Amir Dayi conceived the idea to adorn Rihanna’s belly with diamond belly chains, reaching out to Messika, who quickly produced three custom options. “To bring life into this world is such a gift. Why not highlight that part of your body?” Weaver said. “It’s like, how can you not look at it? So let’s give them something to look at.”

The custom, mesh-top Valentino gown that Rihanna wore to Jay-Z and Beyoncé’s Oscars after-party at Chateau Marmont began as a jumpsuit on the runway. “At a certain point, the pregnancy pants get hard,” Weaver said, so Pierpaolo Piccioli “made it into this beautiful gown” that struck Weaver as “elegant, but cool.” Rihanna initially wore a pair of Amina Muaddi pumps, Weaver recalled, but “towards the end of the night, she was like, ‘Where are my sneakers?'” She then changed into a white pair courtesy of A$AP Rocky’s collaboration with Vans.
