Emma Watson made a fashionable impression at the premiere of her new film Noah last week in New York wearing a beautiful LBD, and the English rose once again upped her game at the film's London premiere last night. Opting for a polished all-white look, the Harry Potter star wore a stunning halter-neck, floor-length Ralph Lauren Collection dress. Adding a seductive edge to her angelic look, Ms Watson's fitted gown featured a sexy thigh-high split and low-cut back, which showed off her toned physique flawlessly. The British actress paired her gown with white pointed-stilettos and a silver clutch and jewellery for the all important red-carpet shimmer. Faultless as ever, Emma's hair was styled in a chic and sleek up-do with her ‘barely there' make-up complimenting her pristine look to a T. If you're feeling inspired by Emma's all-white look and still want a little sex appeal like Ms Watson herself, then opt for the Forever Unique Lizzie Dress in White, for ¬£135, with its asymmetric hem-line, fitted bodice and cut-out detailing, which will give you the fashionista's stunning look for a fraction of the price. For those preferring something a little more demure but love Emma's angelic floor-length look, then try the flowing Forever Unique Kyla Dress in White, ¬£330, for a look that needs no accessories other than the dress' beautifully embellished neckline. If you want to get Ms Watson's stylish red-carpet look but prefer a little colour, then the Forever Unique Plus Tanya Dress in Ivory (Size 16-22), for ¬£470, will give just as much glamour with its strapless fitted-bodice and floor-length style, but will add an extra wow factor with its multi coloured beading. Pair your dress with co-ordinating white stilettoes a la Emma for a minimalistic look, or spice up your look with some statement jewellery.
