Sisters, models and It girls Poppy and Cara Delevingne could be twins, but while at the Burberry Serpentine Summer Party in London yesterday we noticed a distinct difference between the blonde duo. The face of Burberry beauty Cara opted for a matte foundation base with a subtle wash of colour over her cheekbones and mascara while her long, blonde hair was left flowing naturally. She also added a patterned head scarf - the perfect finishing touch to a natural, boho-inspired beauty look. Big sister Poppy worked a dressier style, opting to add styling product to her artfully dishevelled strands and a heavier makeup look, complete with black pencil eyeliner and mascara. Both stunning, no doubt, but which version of pared-back beauty do your prefer - dressed up or dressed down?
