Margot Robbie is showing us that sometimes simple is better. This hairstyle is mainly blow-waved straight but the ends of this look have a bit of a curl in them to allow the hair to move freely when she walks. The color of her hair is dark brunette but she has dyed her hair a medium blonde which looks lovely. You are going to need to touch up your color once every 6 weeks to cover up the regrowth. This look will also be nice with some lighter highlights throughout the hair to give this look some more depth to it. A bit of hairspray is going to ensure that you do not have run away strands of hair in your face.
The middle path opens up her face well which allows you to wear glasses with this look, This is always a factor for some people. This look will not take you long to do in the morning at all!

Makeup-wise, the sky is your limit because this is a simple look. You can do a dramatic smokey eye for a formal occasion or you can do a natural look with a red lip for your workday. Whatever you decide to do, do not forget to contour your face accordingly so that you can show off your best features.
