Carey Mulligan&#x27;s slightly wavy bob looks so romantic paired with a thin headband. Steal her style:    1. Apply curl enhancing cream to damp hair and let it air dry to bring out your natural waves.   2. If your hair is naturally straight, wrap sections of your bob around a 1 1/2-inch curling iron to add waves.   3. Mist your hair with texturizing hairspray, and tousle it with your fingers. Slip on a thin headband to add a chic touch.
