Cardi B's got her sights set on taking over the fashion world, but she's still gonna use her music to kick things off.
Cardi's collabing with Fashion Nova on her own collection, and CEO Richard Saghian tells us they're planning a HUGE launch party for its release ... featuring a live set from the "I Like It" rapper herself.
We're told other big artists are slated to perform as well ... and the event's scheduled for early November.
There's more -- Saghian says it's not a done deal, but he anticipates Cardi will be dropping a brand new single at the party ... which they'll stream live on FN's website.
Cardi began working with the women's clothing store when it noticed she was proudly flaunting their attire on social media. She even raps about them in her song, "She Bad," with the lyrics ... "I could buy designer, but that Fashion Nova fit / All that ass (woo, woo, woo, woo)."
It's also worked with the Kardashians, Amber Rose, Iggy Azalea and Teyana Taylor.
