Dakota Johnson has been hitting red carpets and pavements, promoting her newest movie – Fifty Shades Darker (which is the second one of the trilogy). yesterday, she was in Germany and for the occasion, she wore a black glittery Saint Laurent dress. From the front it looked like a fairly simple dress – nothing to write home about. Then she gave the photogs a glimpse of its back – and clearly that’s where the party was happening. Totally my kinda dress. An undone bun and classic red lippie completed her sexy look.
