And it looks like the stylish singer kept those days in mind when creating her second collection for the British retailer along with designer Adam Selman.
"I needed to make clothes for fat days that I have," Rihanna said in a newly released video that gives us a sneak peek at her new line, which hits shelves on May 25.
But that doesn't mean we can't expect a few pieces with RiRi's signature sex appeal, too.
"I made a piece for everybody in my crew, we all have different body types and different tastes," she explains. "Some are braver than others, but, you know, I think like that because that's how all the women in the world are. We're all different; we all like different things, we all have different occasions, different moods, different body types.
The less adventurous might opt for the cotton pieces the Barbadian beauty claims she will "live in," while those looking for a little more edge can reach for an assortment of tie-dye prints and funky florals that Rihanna made sure were still "gangster" and wearable with "rock 'n' roll stuff."
We wouldn't expect anything less from Rihanna—even on her "fat" days.
