 Facing design clashes with other teams in the 1990s , the club adopted a jersey with a similar design to what became known as the " away jersey " , replacing the blue backing with white , and the outer red stripe with blue . As the club entered the new century , the team began to wear a " foundation jersey " . Although the design differs slightly from the jersey worn in the inaugural 1908 season , it did feature the traditional horizontal striped @-@ design . This jersey is normally worn when the Sydney Roosters face traditional rivals , such as the South Sydney Rabbitohs , or on special occasions such as Anzac Day when the team meets the St George Illawarra Dragons , the product of a team partly formed by the St. George Dragons .
