Jessica Chastain has been the curvy girl's LBD icon for a good few seasons now and when she stepped on to the red carpet for the Hollywood Reporter's Nominee's Night in L.A last night we saw why. The red headed actress poured her famous curves into a black waterfall design dress which featured a waist-whittling peplum middle and leg-lengthening midi cut. No stranger to the glossy pages of a magazine or the flashing paparazzi lights Jessica knows what works for her frame and opted for pointed nude stilettos to add height, simple stud earrings for a little elegance and side-swept tumbling tresses for glamour (we think this will be a big look in Hollywood this season!). For a classic but sexy look like Jess's we recommend taking a look at The Pretty Dress Company's selection of retro style dresses specially designed to make you look like you've dropped a dress size. We love the Black Brooklyn Peplum dress, £101, for recreating the A-lister's look or try Kate Fearnley's Fontaine, £39, for a similar style on a budget. The Pretty Dress Company Black Brooklyn Peplum Dress, £101, Rok Chix Silver and White Diamond Studs, £55, Moda In Pelle Calleen Shoe in Nude Patent, £59.95. Shop all peplum dresses here.
