I'm a hairstylist with a client that has similar sounding hair. She absolutely rocks a ';swing bob.'; One that is slightly shorter in the back than the front, not the Posh bob. I think a bob from mid cheek to anywhere between chin and just above the shoulder is a chic style for ';mature'; women with straight hair. It's also very easy to style with just a blow dryer!

Anything shoulder length or higher would look good. Chin sounds nice!
id keep it that lenght or a lil shorter easy to handle!!
