Celeb hairstylist Sunnie Brook spoke to Bustle about how to achieve the effortlessly tousled and sexy look. According to Brook, the main thing you'll want to recreate is "volume in the front that sweeps across the eye, and then a strong 'C' curve wave that isn't too tight, but has almost a long 'S' shape across the face and around the shoulder." If that all seems a bit confusing, luckily she broke it down.

The first step is to apply a volume-enhancing styling product into your hair when it's still damp and really work it in before drying hair fully. To create even more volume, push your hair onto the opposite side of wherever your part is. So, if your part is on the left, push your hair to the right, and vice versa. Grab your curling iron and curl from the nape of your neck forwards, sticking to small sections to create pockets of volume throughout. 

Hair stylist Samantha Cusick also agrees that its all about the volume, stating that the trick is "curling all your hair in the same direction, and then brushing it out with a soft bristle brush," via Glamour. Rock your waves with confidence for classic Jessica Rabbit sex appeal (red hair unfortunately not included).
