This chic graceful bob haircut has just enough length and volume to soften Parker's features. The cool blonde compliments her complexion, and the blunt ends give it a classy clean look without being harsh.

Easy, breezy, California-girl-blonde waves are just the ticket to give Kim Cattrall's beauty center stage. This hair color compliments Cattrall's skin tone, and the no-fuss hairstyle is perfect for a round face like hers.

This snail-like updo hairstyle would be great if Cattrall could live inside it. Unfortunately, it's just a poorly executed copy of Ivana Trump's signature style, for which Cattrall doesn't have enough hair. What was needed here was a good old-fashioned hair piece.

Round faces look best in simple low-maintenance hairstyles like this one. Styles that are too busy or big or fussy tend to obscure any interesting facial angles, creating a flat featureless appearance. This style gives Cattrall's face room to shine.

Nixon, like her cast mate Kim Cattrall, has a gorgeous round face, not to mention, amazing porcelain skin. This layered bob hairstyle stays out of the way to let Nixon's face take focus. The rich copper color brings her skin to life.
