With 1940s ladylike glamour making a comeback, strapless sweetheart necklines are fast becoming a wardrobe staple. Bandeau dresses ooze femininity and are a seductive yet sophisticated way of flashing some flesh for the upcoming Christmas party season. This style was also the French-favourite on the runway at Paris Fashion Week with the likes of Yves Saint Laurent showcasing striking strapless dresses and Valentino taking on a softer-side with feminine frills on his bandeau styles. And our favourite LBD-loving celebs are rocking this trend too with Heidi Klum showing us lesser mortals how it's done in a sexy strapless ball gown at the Emmy Awards last month and Elizabeth Hurley at Selfridges in London for a Breast Cancer Awareness event in a sparkly strapless tube dress. For your own bandeau-beauty check out Lulu & Co who have updated the classic strapless shape with stand-out stripes and tribal prints and see Herve Leger for sleek and sophisticated off-the-shoulder body-con pieces (black is best for an ultra-slim silhouette). Brands like Reiss and Oasis have some great little black bandeau dresses too which will look great with a structured blazer for a more formal affair. And for a striking strapless investment piece to see you through your party itinerary Coast is your one-stop shop with full on shoulder-flashing frocks as well as some more demure styles with high square necklines and only a hint of collar bone. Always dress your strapless dress up with a huge envelope clutch and sky-scraper heels. Don't scrimp on jewellery either but stick to bangles and rings to leave your neckline centre-stage.
