A perennial tried-and-true favourite, the long bob is the best of both worlds: short enough to pass as a frame your face, but long enough to throw up in a ponytail when it's hot. "With a little bit of length and light styling, you can give yourself a beautiful and effortless wave that is perfect for summer, a FaceTime chat, or a grocery store run," said Nation. "The cool and chic look is great for summer fashion and can easily be achieved with a blowout cream or texturising spray."
