Rihanna has won a court battle against Topshop at the High Court in London.
The Barbadian singer accused the fashion chain of passing off, or attempting to pass off, the garments as being approved by her.
Topshop disputed her claim.
Judge Mr Justice Birss ruled in the Umbrella singer's favour after a hearing in London.
Bringing the action under her full name of Robyn Rihanna Fenty, the US-based celebrity alleged an unknown quantity of T-shirts was acquired by Topshop in 2011 and early 2012 and offered for sale under the name "Rihanna Tank".
Court documents claimed that, after being challenged by the singer's lawyers, Topshop dropped her name on the T-shirt and referred to "Headscarf Girl Tank", and then to "Icon Tank".
The image under attack was taken by a freelance photographer "without her permission" while the popstar was filming a video in Northern Ireland for one of her singles in 2011.
Rihanna was not in court for the proceedings. The European leg of her Diamonds World Tour has just come to an end and she is understood to be taking a break before it continues in China in September.
