Jennifer Aniston on July 20, 2011 arriving for the premiere of “Horrible Bosses” in London. Jennifer’s medium length blonde hair looked great for the event parted to the side with her layered ends framing her face and laying gently on her shoulders. She looked amazing wearing this Valentino dress.

TIP: Mid-length hairstyles are great for fine, thin hair types. It’s easier to add volume with layers and styling products. If you do have big hair this length will require some pouf control. Also this length works with all face shapes.
