English rose Tamsin Egerton stuns in long white gown

British actress Tamsin Egerton looked every inch the goddess at the London premiere for her latest movie The Look of Love earlier this week. Famous for her portrayal of popular student Chelsea Parker in the hit film St Trinian's, off-set Tamsin's style is all about glamour, worlds away from the school uniform she's well known for.

Opting for a floor-length, flowing sheer white evening gown complete with flattering square neckline, ruffles and a black belt, Tamsin clearly knows the golden style rule of less is more. Not only did she score high in the fashion stakes for resisting the temptation to over-accessorise, she also kept her look on-trend by embracing this season's chicest style, monochrome. To recreate S/S13's monochrome look like Tamsin simplicity is key. Mix black with white and watch opposites attract!
