Leighton Meester may be new to the fashion week game but she dresses very well! On Sunday she attended the Diane von Furstenberg show in a yellow dress. Despite being quite young, she manages to look very classic and elegant whilst still retaining her youthful appeal. This is achieved through careful accessories choices. The yellow dress could have been overwhelming but she breaks up the colour with a black belt and adds edgy accessories including zip detail heels to make the look more contemporary. Her clutch is by Jimmy Choo but there are plenty of cheaper alternatives on the High Street. See below to copy her look.
