Rolla's was created by designer couple Andy Paltos and Sarah Gilsenan after spending a decade working for iconic global denim brands. The label embodies the laid-back personality, sexuality and love for jeans of the place where it was born: Australia. Drawing inspiration from 1980's photographers, skateboarders and pub rock bands, Rolla's pares it down and focuses on the classic details and clean lines. It's all about the look, the fit and keeping it simple.
