Alessandra Ambrosio kept the sporty trend going strong while strutting her svelte stuff in LA. The model paired printed skinny jeans by Siwy ($185) with a white tank and matching white Isabel Marant sneakers ($665). Ray-Ban aviators, a gold watch, a white beaded bracelet, and a delicate silver necklace served as cool accessories. She then added even more luxe via her gray crocodile Givenchy bag ($1,729). If it's too cold to wear a tank where you live, just throw on a cozy sweater and coat to top Alessandra's sporty chic.
