Ellen Barkin and Paris Hilton wear the hair well. While I'm guessing Ms. Hilton's hair is just tucked up in the back to give the illusion of a bob haircut, Ms. Barkin's is the classic short in the back, longer in the front with some modern layering.
What this shows is that you can wear this style in a sophisticated way in your 20's, your 40's, or older. It's not a hairstyle that dates you.
You can see we here at Hair Obsessed have a soft spot for the bob--modern, classic, geometrical--this year, it's back. I haven't even mentioned Posh Spice - Victoria Beckham who opened the style up.
