The 23-year-old popstar attended the launch party in Tokyo wearing a floral tracksuit from the range, which featured 3/4 length bottoms and a matching crop top.
Rita paired her patterned suit with a pair of 'Hi My Name Is Yohi' towering wedge sandals, which are from Japanese designer Yohji Yamamoto's Adidas collaboration.
Rita got up on stage and posed for photos, while also waving to fans, blowing kisses and pulling funny faces.
The 'Shine Ya Light' singer jetted into Japan with rumoured boyfriend, US rapper Ricky Hill, and they were both seen making their way out of Narita International Airport.
With her new clothing range, acting career (Rita stars in Fifty Shades Of Grey out next year) and her music success, it seems Rita is set for world domination.
Speaking to Ryan Seacrest last month (12 August), she said: "My main focus is honestly just getting the work finished and finishing off this second album, and coming out as a designer and coming out as an actress.
"Just making sure that the business is all sorted - businesswoman time - so that's what the aim is. All the other things for me is just distraction."
