Rihanna, like us, is a big fan of British brand KTZ. The singer has been spotted rocking awesome gear courtside, and at numerous appearances and nights out on the town. This, however, is definitely her most revealing look from KTZ, which she showed off while enjoying a night out during Paris Fashion Week. She was even hanging out with Mademoiselle Yulia, a Japanese musician and member of the KTZ family. With this head-to-toe look on, let's just say that you can pretty much make out Rihanna's famous underboob tattoo, and nearly everything that the tat is located under. We're already advocates of KTZ and everything the brand is bringing to the table, and Rihanna's outfit last night only made us bigger believers.
