River Island delivers a new style update with covetable looks from its spring-summer 2019 collection. Model Jack Buchanan takes to the studio to showcase both tailored and relaxed pieces from the lineup. Wearing denim, Jack embraces both light and dark washes. The casual staple is juxtaposed with both complementary fashions and more formal options. Polished styles range from a sharp grey suit in a check pattern and a half-zip polo to slim-fit trousers.
