Following September's launch of Somerset by Alice Temperley for John Lewis-the fastest selling brand in the department store's history-this Christmas will see John Lewis exclusively unveil the ultimate Somerset party dress.

Reminiscent of fifties screen sirens and Hollywood glamour,designer Alice Temperley has drawn on her signature style to create a show-stopping master piece for the festive season.

Embellished with intricate swirls of jet black Indian beading,the dress comes in a dramatic floor length version,perfect for formal occasions,as well as a shorter cocktail style.The maxi dress has three quarter length sleeves and comes complete with layers of romantic chiffon for added drama.Both dresses have flattering symmetrical V-necks,front and back-with tulle fan pleating from knee to floor on the longer length.

Jo Hooper,Head of Buying Womenswear,says:"We worked with Alice to create a dress worthy of the red carpet,but that was still affordable.Best paired with the Somerset pony ankle boots or Hazel shoes and a slick of red lipstick,this dress is perfect for every Christmas event,from a cocktail party to New Year's Eve."

The ultimate Christmas party dress from Somerset by Alice Temperleyis available in all John Lewis storesat£299for the full length and£199 for the knee length version.
