Wonder in white: Elizabeth Olsen looked sophisticated as she arrived at the Kiehl’s 2015 Earth Day Project with Benefitting Recycle Across America event in Santa Monica on Wednesday night

The sister of Mary-Kate and Ashley had a refined touch to her mostly white ensemble as she posed for photos at the event in the Santa Monica neighbourhood of Los Angeles.

She wore a white jacket along with a matching midi skirt and completed the outfit with a black top and black leather loafers.

Along with the monochrome outfit she wore her blonde locks down flowing over her shoulders as she had natural, complimentary make-up on her face.

The Godzilla actress did not accessorise with a clutch or designer bag but instead posed while holding classic novel Lord Of The Flies by William Golding.

She was not the only star at the event as Cassie Scerbo put her cleavage on full display in a low-cut black sleeveless jumpsuit.

The actress and singer completed the look with a pair of black leather heels and her raven-coloured locks worn down.
