Oh how Penny from The Big Bang Theory has changed! In recent weeks we've seen the usually red carpet-shy actress gracing some of the most notorious awards ceremonies in a number of memorable dresses. And last night at the Screen Actors Guild Awards Kaley Cuoco looked ravishing in a red prom dress. The blonde bombshell wore a fifties vintage style dress, with a flared skirt that would accentuate any woman’s figure and oozes raw femininity. The red dress had a nipped in waist and thick layered skirt, with a beautiful crocheted layer to add that extra girly touch.Lightly accessorised with a delicate silver bracelet, elegant red clutch bag, and Dorothy-esque ruby red high heels Kaley certainly held her own at the star studded event. Whilst we're not sure about Kaley's homage to Dolly Parton in the hair department we do recommend following in her fashion footsteps with our best-selling Kate Fearnley Buttercup dress, £108, with a fifties flared skirt and nipped in bowed waistband just like the starlet's. Make the look more wearable by showing off your legs and accentuating your frame with light coloured pointed shoes and delicate accessories.
