The woman here does not have a round face, but she does have a hairstyle that is flattering on a round face shape. If you have straight hair, this is a great simple look for your round face that's super easy to style if you aren't high-maintenance. You could even add in side-swept bangs or more layers for an even more styled look.
Note her gorgeous highlights. If you have a great base (dirty blonde hair is the perfect base, according to my stylist at Eva Scrivo Salon in NYC), consider baliage highlights (like Lauren Santo Domingo has here).
