Cardi B launched her second collection with HUGE online fashion retailer Fashion Nova last night with a blowout bash at the Hollywood Palladium. Of course the Brooklyn rapper/singer performed and biggies like Blueface, YG, and more joined her.

Regarding her new line, of course she wore one look from the collection -- a white blazer with skirt featuring zippers that go dangerously close to one's netherregions. Yet Cardi says her clothes are for working women ... we're just not sure where those women are working ...

"Women can wear these to work," she said recently. "[T]his year is workplace, clubbing, brunch, streets, concerts—that’s what I felt ... I have fans that come in all sizes. I felt like it wouldn’t be fair [to make only small sizes]. I took into consideration that there are things that certain people and certain sizes can’t put on, so I made sure that everything is pleasing for every woman’s body—but still sexy." Sexy, indeed!

Check out Cardi's hot set last night -- her hot PERFORMANCE set, not that other hot set she's got! Okay, enjoy that, too!
